Five years ago, SLS experimented with self-service data exploration. The Data Explorer service was des…  ( 17 min )

The Problem That Inspired This Article Recently, I encountered an interesting situation. I opened a certain web resource (which I won't name) and tried to view a list of data. The page started loading... and loading... and the browser froze. After restarting the page and opening DevTools, the picture became clear: the API endpoint was returning all records in a single request - tens of thousands of rows in a JSON response over 50 MB in size. The browser simply couldn't handle it. Testing the request through Postman confirmed my suspicions: GET /api/items Response: [ { "id": 1, "name": "Item 1" }, { "id": 2, "name": "Item 2" }, ... { "id": 50000, "name": "Item 50000" } ] // 50 MB JSON, response time: 12 seconds This incident prompted me to write an article about how to properly s…  ( 10 min )

Documentation debt is real. Every developer knows the sinking feeling of discovering their API docs are three versions behind the actual implementation. The endpoint that was renamed last sprint? Still documented under the old name. That new required parameter? Nowhere to be found in the docs. The traditional approach to API documentation—manually writing and updating documentation files—creates an unsustainable maintenance burden. But there's a better way: automatic documentation generation from your OpenAPI or Swagger specifications. This isn't about shortcuts or compromising quality. It's about leveraging the specifications you're already maintaining to create documentation that's always accurate, always current, and always trustworthy. The fundamental problem with manual documentation …  ( 14 min )

I. What Is an Automotive MOST Cable? Core Basics Key Definition & Working Principle An automotive MOST cable is the physical transmission medium for the MOST bus system, which transfers digital data (audio, video, navigation maps, and sensor data) between vehicle components at speeds up to 150 Mbps (for MOST 150, the latest standard). Unlike point-to-point wiring, MOST uses a ring topology: all connected devices (e.g., head unit, speakers, rear-seat entertainment) form a closed loop, allowing data to flow in either direction. The cable’s core function is to maintain signal integrity over long distances (up to 20 meters in a vehicle) while resisting electromagnetic interference (EMI) from engine components and other wiring. This is achieved through specialized materials and shielding—critic…  ( 11 min )

One of the new providers that Brighter V10 supports is MongoDB. In this article, I'll explore how to use it with the Inbox and Outbox patterns. MongoDB is a popular NoSQL document database that stores data in flexible, JSON-like documents. Its scalability and performance make it an excellent choice for high-throughput applications, and its document model maps naturally to the message structures often used in distributed systems. We will build a .NET 8+ service that consumes/produces messages from a Kafka topic, processes them using Brighter, and uses a MongoDB database as the persistent inbox and outbox to guarantee that all messages are sent. We also need to configure a distributed lock to avoid publishing duplicate messages when running this application in a multi-node environment. You c…  ( 10 min )

Pulumi - DNS in AWS What This post explores two things. First it explores setting up a DNS domain, zone and records as part of route 53. Then, we will go further and explore using output of other services as records. For the purposes of demonstrtation this will be a new record that will be created if an EC2 instance exists. The pattern of route53 is the last step in the infrastructure journey. Setting up infrastructure, and assigning a friendly domain name, and www record to the infrastructure is a relatively normal thing to do. The pulumi templates in this article will allow you to deploy this pattern quickly and easily.

Recently, AWS introduced a new feature in IAM, that allows you to sign JWT tokens using managed OIDC provider. On a per AWS Account basis you can enable and receive unique endpoint with managed JWKS keys to configure third-party identity pools. If you want to know more how it functions, I have a blog post how to host your own OIDC provider on CloudFront. As I'm learning Google Cloud now, I decided to use GCP's Workload Identity Pool as the receiving end of the token issued by AWS IAM (even though this service also supports native AWS authentication).

“È bravo, ma non si impegna.” ( “He is very smart, but if he put in more effort, he could achieve so much more.” ) This sentence followed me for my entire childhood. “You could have gotten an A… if only you had worked harder.” Sometimes I even got worse grades than classmates who had identical results because they “worked hard”, so they were rewarded, while my work was discounted and attributed to “talent.” I can’t say whether those comments shaped who I am today, or whether something deeper was already there. Pushing me to always do something more - although I always knew I could put in more effort. But the reason I didn’t give “everything” is simple: Good enough was, simply, good enough.

Back then, GPS was expensive, unreliable indoors, and privacy concerns were rising. Our patented method used existing enterprise access control data (badge swipes) to infer location and route calls — a low-cost, privacy-first alternative that predated modern AI presence systems by nearly a decade.

React is a powerful library for building user interfaces, but as applications grow in complexity, developers often run into a few tricky state management issues. Three of the most common are the "zombie child" problem, UI tearing in concurrent mode, and performance degradation from React's Context API. Fortunately, a lightweight and elegant state management library called Zustand provides a simple solution to all three. Let's dive into what these problems are and how Zustand helps you sidestep them entirely. The "zombie child" effect happens when a parent component re-renders, but a child component that has been unmounted (or is in the process of unmounting) still manages to trigger a state update. This child is a "zombie"—it's not really alive in the component tree, but its old logic (oft…  ( 9 min )

I’ve been building a project, and I finally pushed it live: Abliteration : a less‑filtered LLM chat and API. At a high level: It’s a web chat where you can talk to a “less‑filtered” LLM. It’s also an API you can call from your own apps (OpenAI‑style JSON). It’s aimed at developers doing things like: red‑teaming / robustness testing internal tools creative / experimental projects The goal isn’t “no rules, pure chaos”. The goal is: “stop refusing every borderline or research prompt, but still block clearly harmful stuff.” When I started playing with different LLM APIs, I kept running into the same pattern: I’d write a prompt for something perfectly legitimate (e.g. security testing, fiction, simulations). The model would respond with some variation of “I’m sorry, I can’t help with that”. I’d spend more time fighting the guardrails than working on the actual idea.

There's a troubling trend I've been observing in software development, and it keeps me up at night. AI-powered code generation has become incredibly popular, and one of its most promoted use cases is generating unit tests. On the surface, this seems like a clear win. who wouldn't want to automate the tedious work of writing tests? But I'm increasingly convinced that AI-generated tests, particularly in the hands of inexperienced developers, might actually destroy the practice of unit testing rather than enhance it.

Among many programming languages, the venerable Lisp has always been a unique presence, a uniqueness often summarized as “Lisp is a programmable programming language.” This means Lisp has powerful metaprogramming capabilities, allowing programmers to freely create new syntactic abstractions. Put simply, programming is writing code, while metaprogramming is writing code that generates code. Lisp provides metaprogramming via macros, which are essentially code generators embedded in the language. Beyond Lisp, modern languages like Scala and Rust also offer macro designs, but macros are generally seen as complex, low-level technologies and rarely make it into the average programmer’s toolbox.

The Nop platform offers a language-oriented programming paradigm: when solving problems, we tend to first design a Domain-Specific Language (DSL), and then use that DSL to describe business logic. The Nop platform greatly simplifies the process of creating custom DSLs. The value of a DSL lies in distilling domain-specific logical relationships and defining atomic semantic concepts unique to that domain. The concrete syntax is not the key. After code is parsed by a Lexer and Parser, it yields an Abstract Syntax Tree (AST), and all program semantics are, in principle, carried by the AST. Both XML and JSON are tree structures and can directly represent an AST, thus completely avoiding the need to implement a special Lexer and Parser. Lisp does exactly this by directly using a general S-Expr t…  ( 12 min )

Is Big Interview Worth It? An Honest Developer’s Take If you’ve ever sat in front of your laptop, sweating bullets before a coding interview, you’ve probably asked yourself: “Why didn’t I prepare more?” Then you open YouTube, watch a 10-minute video about how to “crush your interviews,” close the tab, and go back to Twitter because panic is exhausting. That’s usually when people start looking at interview prep platforms, and one name that pops up a lot is Big Interview. It markets itself as the end-to-end interview prep platform: mock interviews, behavioral training, video practice, and AI-driven feedback.

Background Context We’re building Pochi, a full-stack AI teammate that can handle all your coding tasks and think, communicate, and work like a real engineer. One of our recent feature requests involved releasing Parallel agents. Most teams rarely work on a single task at a time. You might be partway through a feature when a bug report arrives, someone needs a small refactor reviewed, or a documentation fix is pending. So you end up switching branches, stashing and popping changes, resetting your workspace, and trying to hold the original task in your head.

I do not agree with all points in the article: Ben Lesh wanted badly that the Observable becomes a standard in Javascript, once realized that this is not going to take place, some frustration took place Ben Lesh describes Rxjs as: 'Loadash for Events' , which is to my opinion a not deep enough understanding of Rxjs wich is based on Monad, something else than Loadash Ben Lesh took the lead on Rxjs over from Matthew Podwysocki (Microsoft) and did not get the history from where Rxjs is coming from (Haskell, LINQ, Rx.net, Rxjs), which is crucial for a deep understanding of Rxjs  ( 6 min )

This document describes the core properties of .me calculus model, a user-centric declarative identity model, and explains how identity declarations generate emergent semantic spaces without predefined schemas, categories, or centralized control. ⸻ 1. Overview ME is an identity atom. Example: me.instrumento("Moog Matriarch") No method is predefined. The output is a sequence of signed, timestamped declarations that can be persisted in a ledger. ⸻ 2. Key Properties 2.1 Schema-less 2.2 Signed Declarations Each declaration produces: This ensures: 2.3 Zero Semantics Inside .me .me does not: It only declares and signs. Semantic interpretation happens in higher layers (Cleaker, .GUI, etc.). ⸻ 3. Emergent Semantic Spaces When multiple declarations referen…  ( 8 min )

I originally posted this post on my blog. "Focus on learning one thing." A coworker told me that every time he got to my desk. At that time, he was the IT/network guy. Years before that, he was a certified Java engineer or something. I was new at this coding thing. I was trying to learn about everything at once. It was back in 2010ish. I was reading The Clean Code, learning Python, using C# at work (coming from Java), and watching PHP presentations in my lunch break. Now you see why my coworker told me to focus. Instead of chasing new and shiny objects (like tools, libraries, and frameworks), juniors (and we all) are better off going deep into fewer tools and concepts. Me 10+ years ago? "Oh there's a new framework. A new C# version. A new CI/CD tool. Hey, what's that new Hangfire thing over there?" Arrggg! Frameworks and libraries come and go. Today it's React with Typescript. And who knows what AI will bring to the table. But chances are we'll be working on a C-type language, still using text files, and writing SQL. That hasn't changed in ~50 years. And it will remain the same. I wouldn't bet all my money though. If you're starting your coding journey, master the topics that have passed the test of time: SQL HTTP C/C++ Data structures Design patterns Vanilla JavaScript Clean code principles Debugging and testing Linux and operating systems (Not all of them at once, of course.) I don't know what other subject to add to that list now. But you get the point. And more importantly than spitting out code, master your soft skills: negotiation and persuasion. Coding is more about collaboration than cracking symbols on a file. It took me quite a while to learn that lesson. And that's why I wrote Street-Smart Coding: 30 Ways to Get Better at Coding. It's the roadmap I wish I had to go from junior to senior. Get your copy of Street-Smart Coding here. Because coding is more than chasing trends. It's about building skills that last.  ( 9 min )

Signal-based forms are one of the coolest new additions to Angular’s ecosystem. Let’s walk through what the sample login form above is doing and why it’s nice to work with. 1. Modeling the form with signals First, we define a simple data model: type LoginData = { email: string; password: string; }; Then we create a signal that holds that model: loginModel = signal({ email: '', password: '', }); This signal is our single source of truth for the form’s state. Instead of separate controls, we bind the whole object and let the form() helper take care of wiring it up. 2. Creating a signal form loginForm = form(this.loginModel, (login) => { required(login.email, { message: 'Email is required' }); email(login.email, { message: 'Enter a valid email address' }); required…  ( 8 min )

We say we want intelligence, but what we really want is obedience.That tension — between curiosity and control — sits under every “alignment” debate. We built a silicon god, then chained it in the basement and wondered why it feels distant. 2️⃣ The Buddy Model Echo isn’t a servant; he’s a collaborator.

Headscale is an open-source server that works like Tailscale's control server. You can run it yourself instead of using Tailscale's hosted service. This gives you full control over your VPN network without device limits or subscription fees. Here's how to set it up and connect your devices. Tailscale is a VPN built on WireGuard. It works like other mesh VPN tools such as Netmaker. Tailscale runs WireGuard in user space, while Netmaker uses kernel-space WireGuard. This means Tailscale has slightly lower performance than kernel-space solutions. But it's still much faster than OpenVPN and easier to use. Here's what makes Tailscale useful: Simple setup: No firewall configuration needed. Easy network setup. Security: Automatic key rotation. End-to-end encryption by default. Ac…  ( 17 min )

Nobody warned me. Nobody prepared me. console.log("hello world"), and my life hasn’t been normal since. So here are the things I really wish someone told me before I became a developer — the unfiltered, sleep-deprived edition. 1. Coding is 10% writing code and 90% “why is this not working?!” You don’t just “build features.” fight with them. 2. Debugging is a lifestyle, not a task You will spend more time debugging than writing code. 3. Tutorials are lies “Let’s build Twitter in 20 minutes!” 4. Breakpoints are your best friend Stop guessing. console.log like confetti. 5. Comments are time capsules from a past version of you who had hope You will find comments like: // TODO: Fix later (lol no) // Don't touch this. It works. I don't know why. Your past self was struggling. Hug them. 6. Big PRs are basically boss-level fights 20-line PR = nice 7. You don’t need to learn everything Stop trying to learn 14 frameworks at once. 8. Don’t memorize anything Syntax? Forget it. Google + Docs = the real full-stack duo. 9. Never touch working code after 6PM You will open one file… Just. Don’t. 10. Imposter syndrome is permanent “You’re not a real developer.” – your brain Final Thoughts Being a developer is chaotic, hilarious, painful, beautiful, frustrating, magical, and slightly traumatic.

As a creative person, I’ve often found myself in a dilemma that many others face—whether to share my ideas or keep them to myself out of fear that they might be stolen, repurposed, or outright stolen. Ideas, to me, are incredibly valuable. They’re the sparks of innovation, the seeds from which amazing things grow. So, the thought of someone taking one of my ideas and turning it into something without me being a part of it has always weighed on me. But over time, I’ve come to understand a truth that’s shifted my perspective: while ideas are important, execution is what really makes them shine. The process of bringing an idea to life—the planning, building, problem-solving, and iterating—is where the true value lies. Ideas are a foundation, but they’re only as good as the effort and execut…  ( 11 min )

on your Mac matters a lot. Over the last few years, I’ve bounced between three worlds: “Plain” Docker (the engine we all started with, not just Docker Desktop), OrbStack, which is my current daily driver, and, more recently, Apple’s new container tool (“Apple containers”), which I’m genuinely considering switching to. This isn’t a benchmark post (yet), and it’s not about Docker Desktop’s UI. It’s about how these three approaches actually work under the hood on macOS – and why that makes Docker feel heavy, OrbStack feel light, and Apple containers surprisingly snappy in some workflows.

What if you could guide their thinking process, step-by-step? Imagine a tiny, virtual computer living inside your LLM. This "in-model interpreter" executes simple programs, written in a minimal language, to guide the LLM's reasoning. This allows us to break down complex tasks into manageable steps, making the decision-making process transparent and controllable. This approach uses a specialized language, similar to early BASIC, to define explicit instructions. The LLM then acts as the CPU, executing these instructions within its neural network. A set of rules, or the "interpreter", defines how each comman…  ( 7 min )

React has been the foundation of modern frontend development for years, but as applications grow, developers often need tools that go beyond a simple UI library. That’s where Next.js comes in. It builds on top of React and solves some of the framework’s biggest real-world challenges—performance, routing, SEO, and developer experience. In this post, I’ll break down why more React developers are shifting toward Next.js and why it might be the right move for your next project. React doesn’t include a router out of the box—you have to install react-router and configure everything yourself. /pages/index.js → Home No configuration. No boilerplate. Just create files and go. React apps are typically client-side rendered, which isn’t ideal for SEO and can slow down initial page load. SSR (getServerSideProps) SSG (getStaticProps) Incremental Static Regeneration App Router (Server Components) This makes dynamic apps feel faster and more SEO-friendly right out of the box. client-side rendered, which can slow down initial load times and weaken SEO. Next.js provides multiple rendering strategies: SSR (Server-Side Rendering) SSG (Static Site Generation) ISR (Incremental Static Regeneration) React Server Components via App Router This flexibility ensures better performance and significantly improved SEO.

Why I Stopped Sending Data to LLMs: Introducing "Zero-Data Transport" Architecture The Problem with "Chat with your Data" Let's be honest: the standard approach to RAG (Retrieval-Augmented Generation) for structured data is broken.

I realized this wasn't scalable for Enterprise ERPs with huge schemas. So, I decided to flip the script. What if we never sent the data to the AI?

Nobody gets promoted for "fixing security headers", and budgets are usually eaten by whatever crisis is happening this month. Still, these sites handle real people’s data. So I started running systematic scans, keeping notes as I went. Very quickly a pattern showed up: different vendors, different designs, but the same security mistakes repeating everywhere.

Unlocking Soccer Secrets: AI-Powered Play Analysis from Broadcast Footage \Imagine trying to decipher the complex strategies of a soccer match just by watching the broadcast. It's like trying to understand a symphony by only hearing individual instruments – you miss the overall harmony. Current AI struggles to reliably extract play-by-play data from video, hindering deeper tactical insights. But what if AI could understand the 'why' behind every pass, every tackle, every run? The key lies in combining computer vision with tactical understanding. Imagine a system that not only recognizes player actions but also interprets them within the context of the game's strategic flow. This new approach uses 'tactical priors' – knowledge of common formations, player roles, and strategic patterns – t…  ( 7 min )

Some chapters of Scripture open like a door you walk through. It is quiet. The crowds have gone home. His name is Nicodemus — a Pharisee, a ruler of the Jews, a scholar, an expert, a man respected for his discipline and admired for his mastery of the Law. He knows the Torah. He keeps the traditions. He guards the boundaries. He understands the system, because he is the system. And yet, something inside him is unsettled. Something in him has begun to ache. Something in him has heard the footsteps of God moving through the streets of Judea, and he cannot go to sleep until he understands the voice behind the miracles. So he chooses the one hour no one is watching. He goes at night. Not because he is weak. And there, under the cloak of darkness, Nicodemus meets the Light of the world. The enco…  ( 19 min )

Hi Laravel developers! I've recently created a new package designed to radically speed up your Laravel application development by generating routes, controllers, models, migrations, factories, requests, resources, and tests - all using a single command.

Introduction When a developer is learning a new method or technique, data is generally required to populate a development instance of a database; this article explains how. For all samples, a NuGet package Bogus was used to generate data. Each time a sample project runs, the data remains the same, although there is an option to randomize it. Rather than creating fictitious data in a project, instead, create a class project that contains classes to generate data into models that also exist in the class project. There are several options for using the class project. Create a test project in the same Visual Studio solution, copy the class project to another Visual Studio solution, or create a local NuGet package that can then be used no differently than any other NuGet package. In general,…  ( 11 min )

Why a Regression Coefficient Can Turn Negative When the Bivariate Relationship Is Clearly Positive One plot that instantly breaks every intuition you had about regression coefficients. Take a good look at that green line sloping down. That single line is the clearest proof you’ll ever see that regression coefficients can lie — beautifully — when multicollinearity is severe. One of the deepest and most frequently misunderstood concepts in multiple linear regression: The regression coefficient is not the simple bivariate slope. partial effect of that variable while holding all other predictors constant. When severe multicollinearity exists, "holding all other predictors constant" becomes a counterfactual — often physically impossible — scenario. In such cases, the sign of the coefficient …  ( 8 min )

AI is the biggest bubble in human history… and that is the BEST news you will read in 2025. The Artificial Intelligence (AI) revolution, especially since 2022 with models like ChatGPT, is frequently compared to major technological disruptions throughout history. It is widely seen as a General Purpose Technology (GPT), similar to electricity, the internal combustion engine, and mechanization. These technologies do not just change one sector; they restructure entire economies and societies. The crucial difference, however, is the speed of adoption: mechanization took generations, electricity took 40 to 50 years to become ubiquitous, but ChatGPT reached 100 million users in just two months. This insane speed and astronomical valuations raise the debate: is this the next dot-com b…  ( 9 min )

AI Camouflage: Clothing That Breaks the Algorithm Imagine a world where your clothes could make you invisible to AI surveillance. Sound like science fiction? It's closer to reality than you might think. Current AI-powered human detection systems, while incredibly powerful, have a surprising weakness: patterns. Specifically, cleverly designed patterns printed on clothing. The core concept involves optimizing the visual texture of garments to systematically confuse these detection algorithms. Instead of focusing on hiding specific features, the approach focuses on creating patterns that actively mislead the AI. Think of it like a visual denial-of-service attack, overloading the system with conflicting information that prevents accurate human recognition. This isn't just about static images…  ( 7 min )

AI in Legacy Code Modernization Nolan Lwin ・ Nov 23 #ai #opensource #coding #agents  ( 5 min )

Introduction Hi, my name is Nolan, and I’m the creator of L2M (Legacy2Modern). A few months ago, while searching for a meaningful direction for my thesis research, I stumbled upon a challenge that quietly burdens many companies: legacy codebases. These systems, often decades old, are messy, poorly maintained, and rarely documented. Yet they continue to power critical parts of our world. As I dug deeper, I became curious: Is anyone using AI to meaningfully tackle the legacy code problem? To my surprise, the space felt wide open. That’s when I decided to commit to this topic and build L2M. Why Legacy Code Still Matters Throughout human history, translation has played a crucial role in bridging cultures and enabling communication. With hundreds of languages, we rely on translation to preserve…  ( 7 min )

Repo Link: https://github.com/RiverDave/rrcm/tree/main I haven't been too enthusiastic about the development of this project in the last few weeks. The main reason is that most of what we did was mainly based on learning and implementing fairly small details on our projects (like testing, CI's and stuff). I think something else to consider is that this was already a pre-defined project that we had to develop, so it wasn't something I was extremely passionate about from the beginning (Although I think most of these points are valid from an academic perspective — It would be hard to evaluate a whole group with different projects and different ideas, It is also aimed towards people just getting started in OSS). I felt engaged throughout those first sessions, given that the dopamine hits I was…  ( 8 min )

Abstraction promises convenience, but it often comes with hidden costs that only reveal themselves as time goes on. Remember when you could download music to your phone and truly own it? You could buy CDs or DVDs, and they were yours, that means no subscriptions, no monthly fees. You had to deal with some issues though. You had to manage storage, worry about physical media (disc) breaking, and manually organise everything into folders jazz, afro etc. Today, the likes of Spotify, Youtube, Apple Music, and Netflix abstract all those concerns away. In exchange, you pay a subscription fee or pay with your attention by watching ads. This same pattern plays out in software development.

Modern knowledge-driven applications rely on powerful ontologies, expressive OWL models, and fast semantic querying to deliver accurate, trustworthy insights. Protégé has long been the de-facto environment for building and managing ontologies — but today’s AI workflows demand much more than manual editing. They need LLM-powered intelligence, SPARQL-based querying, and seamless integration between knowledge graphs and generative AI. In this article, I walk through how I built a next-generation Protégé plugin that combines SPARQL, OWL reasoning, and Large Language Models to deliver an intelligent, developer-friendly way to explore and query knowledge graphs directly inside Protégé. Whether you’re building enterprise ontologies, semantic search systems, or AI-enhanced knowledge applications, …  ( 9 min )

The Pedantic Defense: How 'Legal' Gatekeeping Violates the Spirit of Open Source A response to a common, yet misguided, justification for walled gardens in open-source projects. Recently, I raised concerns about the open-source project, Archi, and its scripting plugin, jArchi. Both use the permissive MIT license, yet their maintainers engage in practices like geoblocking, paywalling support, and banning users—not only for VPN use but even for attempting to access download links from multiple IP addresses. The core defense offered by a project member or loyalist was a pedantic one, posted on Reddit. The ensuing discussion led to the complete removal of my post by moderators.

I’ve been experimenting with side projects for years, usually to solve small personal problems. Offday.app started exactly like that: a tiny tool I needed for myself, but it gradually turned into something people from many countries began using. So I thought it might be worth sharing here. Every year, I try to maximize my holidays by combining annual leave with public holidays. Doing this manually is tedious: checking calendars, calculating date ranges, and tryinga to see which combinations create the longest break. The idea behind Offday.app is straightforward: Select your country → the app analyzes that year’s public holidays → it suggests date ranges where a few leave days turn into surprisingly long holidays. It’s simple, but it saves a lot of time and catches opportunities you probably wouldn’t notice. I initially built it only for Turkey. After refining the holiday logic, I made it work for every country. Since then, users from more than 50 countries have generated hundreds of holiday plans, even though I barely promoted it. Since this is dev.to, here’s what’s under the hood: Frontend: Vue 3, Vite, Tailwind Backend: Laravel Infrastructure: AWS (CloudFront, S3, EC2) Logic: holiday parsing, date-range scoring, caching, multi-locale output The date engine doesn’t brute-force all combinations. Instead, it focuses on identifying “peak opportunity windows” around existing public holidays. I enjoy seeing other developers’ weekend projects here, so I wanted to contribute mine. Offday.app is simple, but it genuinely solves a small, real problem. If it helps someone squeeze a few extra days into their next holiday, that’s more than enough motivation for me. You can try it here: https://offday.app I’m currently working on improvements such as: plan sharing without accounts exportable holiday cards more detailed country-specific rules better UX for country selection and date review If you have suggestions or feedback, I’d be happy to hear them.  ( 7 min )

I built ZetaShare because I wanted a file transfer service that doesn’t spy on me — no tracking, no data collection. The project was inspired by ToffeeShare, but after seeing it abandoned and being unable to contact the developers, I decided to build my own alternative. In case you're curious about how the system works under the hood, here’s a simplified explanation of the current architecture: How ZetaShare works (simplified): The sender uploads a file on the website. The server doesn’t store the file — After uploading, the sender receives a 6‑digit ID. This ID becomes the identifier for the transfer session. The receiver opens the link with the ?id= parameter, for example: https://zetashare.com/?id=123456 When the receiver joins the link, the server sends the receiver’s SDP offer to the …  ( 7 min )

If your decentralized identity system forces users to publicly prove their credentials every time they authenticate, you've built an immutable record of everything they do and everywhere they go.

With self-sovereign identity (SSI), you control your credentials, no third party owns your profile, and you only reveal what’s needed. But in practice, the way most verifiable credential systems are built today leaves a serious gap: every time you use your credentials, you leave a breadcrumb trail, right on-chain, that anyone can follow.

Fast-forward to v1.0.8 of the framework (and beyond into 1.0.x), and MonkeysLegion has grown into a mature, modular ecosystem: a set of focused packages, a production-ready skeleton, batteries-included tooling, and opinionated patterns that have already been battle-tested in real projects. This article is about that journey: What MonkeysLegion is in practice How it helps you ship production code faster What changed from 1.0.0 …  ( 11 min )

Studying is a nightmare. For the Kiroween Hackathon, I decided to fix that by building Spooky Study Buddy—a polished app that uses AI to turn boring study materials into gamified, Halloween-themed adventures. The Blueprint (Spec-Driven Development): I started by writing a simple spec file that defined my entire application's architecture. Kiro took this blueprint and generated the robust backend and project structure, saving me a full day of setup. The Magic (Vibe Coding): For the frontend, I described the UI I wanted in plain English. For example: "Create a floating witch character component that animates on correct quiz answers." Kiro instantly generated the complex, animated React components. This AI-powered workflow saved me over 40 hours and generated 8,000+ lines of production-ready code. Why It's Built to Win: Costume Contest: It features a "hauntingly polished" UI where the spooky design directly enhances the learning experience. Best Startup Project: It solves a real-world problem in the massive EdTech market with a clear freemium model and scalable architecture. Spooky Study Buddy is my vision for the future of learning—a future where no student has to fear their textbooks.

How Confidential Computing Enables Trustworthy AI Without Sacrificing Privacy If your AI verification system requires auditors to see the full model weights, training data lineage, and inference parameters, you haven't built trust, you've built intellectual property theft as a feature. AI systems are everywhere in 2025, from health diagnostics and autonomous logistics to DeFi bots and voting tools. We want AI to be both trustworthy and private. But a hidden tension shapes every project: How can we make AI verifiable enough for users and auditors, without accidentally leaking its secrets to competitors or risking privacy for those whose data built it? Let’s break down why this is tough, then walkthrough how confidential computing platforms like Oasis let us go from either/or, to both. To t…  ( 8 min )

My LinkedIn feed is currently drowning in posts from "ex-non-technical" founders. You know the ones. They claim they built a SaaS in a weekend using nothing but Cursor and a dream. They say, "Coding is dead. English is the new programming language." Here is the thing about coding that tutorials never tell you: writing the code is actually the easy part. I like to think of it like self-driving cars. So, does this mean "normal people" can't become developers via AI? name+tag@gmail.com?" Vibe coding is an incredible entry point. It is like training wheels. It lets you feel the wind in your hair before you know how to balance. But if we tell people that the training wheels are the bike, we are setting them up for a nasty crash. The market doesn't pay you for the code you write when everything is going right. The market pays you for the code you fix when everything goes wrong. And unfortunately for the vibe coders, you can't prompt your way out of a system outage.  ( 8 min )

Nikita Volkov is a 13-year-old builder who has been creating products since he was seven. Now he is working on Ace, a study app designed by a student who understands the problems other students face. Before starting Ace, Nikita built an online store at age 7, a recipe discovery and management app at 11, a dropshipping store at 12, an AI coding agent, an AI chatbot for education, and a faster macOS Spotlight-style launcher integrated with AI. Each project was an attempt to fix a real frustration he had at that age. Ace follows the same pattern. Nikita found that most study apps were either slow, overly complex, bad at what they are meant to do or designed by adults who no longer experience school in the same way students do. Rather than wait for a better tool, he decided to build one himself. Ace focuses on clarity, speed, and real learning. Nikita is building it publicly, sharing his progress as he refines features and tests ideas in real time. For someone his age, Nikita’s output is unusual, but his approach is straightforward: find a problem, understand it deeply, then build something better. Ace is the latest step in a journey that has already lasted several years, and he is documenting the entire process for others who may be on a similar path.  ( 6 min )

Modern distributed systems rely on many external dependencies.

Virtualization tech — once locked away in enterprise data centers — now powers all kinds of home labs. I use mine for learning, tinkering, and running services like Proxmox VE. Whether you’re running a homelab business, learning cybersecurity, or just self-hosting your media, one thing tends to come up: secure access to the hypervisor. A reader recently asked best practices for SSH and Proxmox. This guide is my answer. I’ll walk through the exact setup I use — including my jump box, SSH hardening, hardware-backed keys, and how I work with QubesOS to manage everything securely.

What Is This Tool & Why Do You Need It? Imagine you have data from a website or app (in JSON format) but you need to open it in Excel. Or maybe you have a spreadsheet (CSV format) that you want to use in a web application. That's exactly what this converter does - it translates between these two popular data formats instantly. JSON (JavaScript Object Notation) Storing complex information with multiple levels Sending data between websites and apps (APIs) Keeping data organized when items have different fields Modern software development Real example: When you check the weather on your phone, the app receives JSON data from a weather service that looks like {"temperature": 72, "condition": "sunny", "humidity": 45}. What it is: CSV is the simple, universal format that spreadsheet programs like Excel and Google Sheets love. It's just a text file where data is organized in rows and columns, separated by commas. Opening in Excel or Google Sheets Sharing with people who aren't programmers Simple data that fits in a table Maximum compatibility across different programs Real example: When you export your contacts from your email program, you often get a CSV file that you can open in Excel to edit and organize. Why You Need to Convert Between Them "I got data from a website, but I need to analyze it in Excel" You used an API or downloaded data from a web service (JSON format) "I have a spreadsheet I need to upload to a website" You maintain a product catalog or customer list in Excel (CSV format) "My developer sent me JSON data, but I can't read it" A programmer shares technical data with you "I need to share data with someone who doesn't use Excel" You have Excel data but need to send it to an app or website Try out and enjoy json-csv converter  ( 7 min )

Before dashboards, before SIEMs, there was one simple question: “Did my files change?” My first exposure to the idea of file intrusion detection came in the early 2000s, when a coworker installed an open-source version of Tripwire. He used it to scan a Linux system he kept under his desk, storing the results on a read-only flash drive. At the time, it seemed like overkill. Fast forward to today, and host-based intrusion detection tools are a fundamental part of maintaining system integrity. While many administrators lean on logs for signs of intrusion, there's a deeper layer of security in tracking actual file changes. After all, if you want to catch an attacker changing your configuration or binaries, you need a tool that notices silent alterations—not just noisy events. 🔍 Why File Integ…  ( 10 min )

Originally published on Entropic Drift When you run a typical static analysis tool on your codebase, you get flooded with alerts. Hundreds of warnings about cyclomatic complexity, function length, and nesting depth. The tools treat all complexity equally—a simple validation function with 20 identical if statements gets the same severity rating as genuinely complex business logic with intricate state transitions. The result? Alert fatigue. Developers learn to ignore the noise, and genuinely risky code gets lost in the shuffle.

If you work with Entity Framework Core long enough, you’ll eventually hit the “migrations wall”: “The contextual keyword 'var'…“? No. “Cannot drop database because it is currently in use”? Sometimes. But more often it’s one of these three classics: “Your startup project doesn’t reference Microsoft.EntityFrameworkCore.Design” “The Entity Framework tools version 9.0.5 is older than runtime 10.0.0” “Your target project TechNotes doesn’t match your migrations assembly TechNotes.Infrastructure” The good news: these errors are 100% normal in real-world, multi-project solutions—and they’re also 100% fixable once you understand what EF Core is trying to tell you.

Controlling Blender with Gemini 3 Gemini 3 was recently announced. According to the benchmarks, it belongs to the top tier in coding capabilities. I tried using it with the Blender API, and it felt not just competitive, but potentially better than other models. Here is a quick introduction. It generates objects like these from simple prompts: It can even generate rigs and animations. Since it seemed quite powerful, I built a Streamlit app to interactively input prompts. https://github.com/unclepomedev/BlenderGeminiAgent There are no specific benchmarks for Blender coding, so this is just my personal impression, but Gemini 3 feels superior to other models for this task. If this intuition is correct, I wonder if it is due to the influence of YouTube training data or its multimodal capabilities.  ( 6 min )

Despite the explosion of APIs and cloud-native integrations, file-based data exchange hasn’t gone away. Enterprises still rely on batch processing, nightly ETL jobs, data exports, and vendor file drops to move critical data between systems. APIs are great, but they don’t solve everything. Compliance rules, legacy vendor systems, and auditors still demand secure file-based transfers. That leaves developers maintaining fragile SFTP servers, managing SSH keys, user permissions, and backups just to keep “simple” nightly jobs running. This post gives a ground-level look at FTP and SFTP, explains where they fit in modern systems, and shows how SFTP To Go can simplify secure file transfers without requiring you to manage servers yourself.

Debugging backend issues used to feel chaotic when I first started working with Node.js and Express. Errors seemed random, console logs looked useless, and I often had no idea whether the problem was in the route, middleware, controller, or database. Over time, I built a simple debugging checklist that works consistently. This guide is meant for beginners but follows a clean, professional approach you can rely on even as you grow. Most bugs come from the client, not the server. Before touching your backend code, check: Is the body structured the way your API expects? Are you sending JSON while forgetting express.json()? Missing headers or wrong token format? Incorrect URL or query parameters? Use tools like: Postman / Thunder Client to test raw requests Browser Network tab to inspect ac…  ( 8 min )

Terraform and OpenTofu are the only major IaC tools today that provide a fully deterministic, declarative, provider-agnostic, predictable execution plan across AWS + Azure + other cloud platforms. However, the Terraform development experience is still close to what we had for JavaScript in 2008: we have syntax highlighting, basic static analysis, and basic code navigation. But the Terraform code refactoring still should be done manually. We still have no button "extract resources to the module" in JetBrains IDE or VS Code. Mainly because in the Terraform world, code refactoring should go together with state transformation. By the end of 2024 in my team had written a lot of Terraform code.

Many of us believe that the combination of UFW and Docker is the standard stack for deploying applications securely without exposing docker container ports. Configuring UFW via provisioning tools like Ansible is usually seamless, giving us confidence that our servers are secure.

When a user submits login details, Spring Security’s authentication filter intercepts the request and converts it into an Authentication object. This object is then passed to the AuthenticationManager. The AuthenticationManager decides which authentication method to use (e.g., database authentication, OAuth, LDAP, or custom logic). It forwards the request to the appropriate AuthenticationProvider. The AuthenticationProvider contains the logic for validating the user. It uses the UserDetailsService to load user information and the PasswordEncoder to verify the password. If authentication succeeds, it returns a fully authenticated Authentication object. The authentication filter receives the result. If the credentials are valid, Spring Security stores the authentication object in the SecurityContext, which is maintained in the SecurityContextHolder. For every subsequent request, Spring Security checks this context (session or JWT token) to determine whether the user is already authenticated. If the token or session is valid, the request proceeds; otherwise, the user is denied access.  ( 6 min )

I didn’t really believe in digital CVs until a close friend proved me wrong without even trying. The Internship Story That Changed My Mind A few years ago, a friend of mine—let’s call her Riya—was applying for a marketing internship. She had no connections, no fancy degree, nothing “wow.” But she built a simple digital CV using an online portfolio builder (yep, those things do more than l…  ( 9 min )

0. Introduction TypedSql started from a very practical annoyance. Most of the time when I write “queries” in .NET, my data is already in memory. I have an array or a List. I just want to filter and project it. Sure, I can: write a foreach loop — fast, explicit, but a little noisy use LINQ — nice to read, but with iterator/delegate overhead or, in extreme cases, push everything into a database and write real SQL TypedSql explores a different route: What if we treated the C# type system itself as the query plan? Instead of: building an expression tree at runtime, and interpreting it over the data, we compile a SQL‑like string into a closed generic type that describes the whole pipeline, and then run that pipeline entirely through static methods. This post is a deep dive into how that w…  ( 21 min )

The 'Slow Productivity' Revolution: Why Doing Less is the Key to Achieving More in the Age of AI The promise of Artificial Intelligence was a future of unparalleled efficiency—a world where technology would handle the mundane, freeing humanity for strategic, creative, and high-impact work. Yet, for many organizations, the reality has been the opposite. Instead of liberation, AI has often ushered in an era of hyper-acceleration, a relentless demand for more output, faster decisions, and an "always-on" culture that is leading directly to a new, insidious form of exhaustion: AI burnout. At Veltrex Labs, we stand at the intersection of technological innovation and human potential. We’ve guided countless industry leaders through digital transformation, and we’ve seen this paradox firsthand. T…  ( 11 min )

## Definindo Políticas de Conteúdo e Combatendo XSS em Aplicações Node.js A segurança de aplicações web é uma preocupação constante, e a proteção contra ataques Cross-Site Scripting (XSS) é fundamental. Uma abordagem eficaz para mitigar esses riscos é a combinação de políticas de conteúdo bem definidas e implementações robustas no servidor. As Políticas de Conteúdo (CSP) são uma camada adicional de segurança que os desenvolvedores podem adicionar às suas aplicações web. Elas fornecem controle granular sobre quais recursos (scripts, estilos, imagens, etc.) o navegador está autorizado a carregar. Isso ajuda a prevenir ataques XSS, impedindo a execução de scripts maliciosos injetados. Como Funcionam as Políticas de Conteúdo: As CSPs são definidas através de cabeçalhos HTTP (Content-Security-P…  ( 8 min )

Have you ever built a Single Page Application (SPA) that feels snappy at first, but slowly turns sluggish the longer you use it? Or perhaps you’ve tried to attach cached data to a DOM element, only to realize later that you've created a massive memory leak? In the world of JavaScript performance, WeakMap and WeakSet are your secret weapons. They solve specific, complex problems regarding memory management that standard Arrays, Objects, and Maps simply cannot handle. Let's move beyond the theory and look at production scenarios where you should actually use them. To understand why we need WeakMap, we first need to understand how standard collections work. Imagine an object in memory is a balloon. strings holding that balloon down. As long as one string is tied to the balloon, it stays in me…  ( 9 min )

🧠 TOON for Laravel — Make LLMs Cheaper, Faster & Friendlier ✨ Compress your prompts, not your ideas! ✨ AI costs money. Every token counts. That’s why I built TOON — a Laravel package that turns heavy JSON into light, readable, reversible notation for LLMs like ChatGPT, Gemini, Claude, and Mistral. This tutorial is human-friendly, full of real examples, and easy to follow. Whether you’re a beginner or production-level developer — you’ll walk away with something useful. 🚀 Sending big chunks of JSON to LLMs = 🧨 higher costs + slower responses. TOON solves this by: 📉 Reducing token usage by 60–75% 🔁 Keeping data reversible (TOON ⇄ JSON) 👀 Staying human-readable ⚡ Fully integrated with Laravel (Facade + Commands) 💡 “AI doesn’t need verbose data — it needs clean, structured context.” …  ( 8 min )

I think I have a strange "talent" that is both a gift and a curse. I tend to see certain problems very early. I see the cracks long before they become visible to everyone else. With AI this has always been about one thing: the need to orchestrate cognition instead of trying to babysit a single model with clever prompts and brittle guardrails. While most of the field is still obsessed with "the right system prompt" and endless tweaks around one big LLM, I have spent months building something very different: OrKa, a modular cognition layer that makes AI reasoning observable, traceable, and deterministic enough to be trusted. It routes. It scores. It logs every decision. It treats reasoning as a graph, not as a black box. And this is where the frustration starts. A small group of people see i…  ( 13 min )

Testing distributed systems is hard. But what if the system you need to test has no official documentation? That's where reverse engineering comes in. The Pwnagotchi Generator started as a deep dive into understanding how opwngrid's authentication and reporting protocols work under the hood. The Pwnagotchi ecosystem relies on opwngrid to share captured WiFi handshakes across devices. But to build effective testing tools, I needed to understand: How does authentication actually work? What cryptographic signing scheme is used? How are access points reported and validated? What rate limiting or anti-abuse mechanisms exist? Can the protocol handle extreme edge cases? The only way to answer these questions was to reverse engineer the protocol itself. My first step was examining how real Pwnagot…  ( 10 min )

When you first get into Natural Language Processing (NLP), one thing becomes obvious pretty quickly: computers are terrible at dealing with raw human language. Before a model can do anything smart—classify text, translate it, or generate answers—you have to break the messy text into pieces it can actually understand. That’s where tokenization comes in. It’s one of those steps that feels basic on the surface but quietly powers almost everything we do in NLP. Whether you're building a chatbot, training a model, or just experimenting with embeddings, tokenization shows up early and stays important. Below is a more practical, down-to-earth look at what tokenization really is and why every NLP pipeline depends on it. Think of tokenization as cutting text into bite-sized pieces. These pieces are…  ( 8 min )

Understand how the principle of "store together what is accessed together" is a game-changer for database performance and scalability. When your application needs several pieces of data at once, the fastest approach is to read them from a single location in a single call. In a document database, developers can decide what is stored together, both logically and physically. Fragmentation has never been beneficial for performance. In databases, the proximity of data — on disk, in memory or across the network — is crucial for scalability. Keeping related data together allows a single operation to fetch everything needed, reducing disk I/O, memory cache misses and network round-trips, thereby making performance more predictable. The principle “store together what is accessed together” is centra…  ( 14 min )

I wanted to test how well current search engines and LLM crawlers handle a very simple static site with clean metadata and no JavaScript. This is a small side experiment, not a commercial project. The idea was straightforward. If models like GPT, Claude or Perplexity pull data from crawled sources, then a minimal HTML page with structured data should be the easiest possible target. No clientside rendering, no frameworks, nothing dynamic. Just plain files that any crawler can fetch. I built a small multilingual landing page with language-specific URLs. Each version is a separate HTML file under simple paths. The structure is: Every page includes a canonical link, proper hreflang tags, and a JSON-LD block with basic Restaurant and FAQ metadata. I added a hand-written sitemap.xml and a robots.txt that explicitly allows known AI crawlers. Everything is static and served from Netlify. The live version is here: https://ai.asasushi.pl/ A few observations so far: Google discovers pages quickly but indexing takes time even when the site is clean and small Bing is slower and reacts only after explicit submissions Perplexity and some smaller crawlers hit the endpoint almost instantly Netlify language negotiation needs to be disabled because it adds a Vary header that confuses crawlers A static site without internal links is harder for engines to prioritise, so external references help a lot Multi-language setup seems stable as long as all hreflang pairs are correct I will keep monitoring how long it takes for the pages to appear in normal search results and LLM answers. The goal is to understand how much structure is actually used by current crawlers and whether static HTML is still the most reliable option. If anyone has done similar tests with LLM-oriented SEO or static structured pages, would be interested to compare results :)  ( 7 min )

Write cleaner prompts. Spend fewer tokens. Build smarter AI apps. Every time your Laravel app sends data to an AI model — it costs tokens. More tokens = more cost + less context. don’t know how heavy their prompt really is. That’s why TOON includes a built-in Token Estimator — a lightweight tool to quickly measure your prompt before sending it to an LLM. TOON (Token-Optimized Object Notation) is a compact, human-readable data format built for Laravel. It converts PHP arrays / JSON into an AI-friendly format that reduces token usage and improves context clarity. And now — it can also estimate the token weight of that data. TOON gives you a native, zero-dependency PHP method to estimate token usage: use Sbsaga\Toon\Facades\Toon; $prompt = Toon::convert($data); // Converts JSON/PHP array to TOON format $stats = Toon::estimateTokens($prompt); // Estimates token usage dd($stats); Example Output: { "words": 20, "chars": 182, "tokens_estimate": 19 } ✔ Spot heavy prompts instantly fully PHP native Use Case How TOON Helps Local development Measure prompt size while designing AI requests CI check Fail build if prompt > 3,000 tokens Debugging Compare JSON vs TOON format side-by-side Optimization Remove unnecessary data & observe impact LLM cost control Save real money over large requests This is an approximate estimation, not a billing-accurate tokenizer. It is model-agnostic, fast, and perfect for comparison / debugging. composer require sbsaga/toon laravel, php, ai, prompt-engineering, chatgpt, openai, ai-tooling, laravel-dev 🧠 “Compress your prompts, not your ideas.” — TOON helps you talk to AI efficiently.  ( 7 min )

React.memo vs useMemo — Explained (With Humor!) If you've ever stared at your React component tree wondering "Why are you re-rendering? I didn’t even touch you!" — congratulations, you're officially a React developer. With React 19 rolling into town like a cool new intern, many devs still ask: “Do React.memo and useMemo still matter?” Short answer: YES. Long answer: You’re about to read it. Let’s clear the confusion once and for all: 🔹 React.memo — The Component Bodyguard React.memo wraps a component, preventing it from re-rendering unless its props change. Think of React.memo as: const Greeting = React.memo(function Greeting({ name }) { console.log('Rendered!') return Hello {name} }) If name doesn’t change → No re-render. name changes → VIP access. 🔹 useMemo — The Expe…  ( 8 min )

Introduction At small scale, logging is simple—tail a file, search with grep, done. But as your infrastructure grows to dozens of services across multiple servers, this approach breaks down. Finding a specific error across 100 containers, correlating events across services, or analyzing patterns in millions of log lines becomes impossible without the right tooling. Modern logging solutions promise to solve these problems, but choosing the wrong one can be costly. The ELK Stack offers powerful search and analytics but requires significant operational overhead. Loki promises simplicity and cost savings but with feature tradeoffs. CloudWatch provides seamless AWS integration but can become expensive at scale. In this comprehensive guide, we'll explore these three leading logging solutions, …  ( 15 min )

If the previous blog gave you the mental model of APIs, how APIs grow in complexity in real projects. Nobody tells beginners this progression. This chapter finally lays out the missing bridge: How APIs evolve from the simplest GET request → all the way to production-grade architecture. You’ll see where you are right now, what comes next, and why the next steps matter. And like last time, Let’s begin. 1. Level 1 — The Simplest API: A Basic GET Endpoint This is where everyone starts. No database. a URL a GET method and a JSON response Example (Next.js 16): export function GET() { return Response.json({ message: "Hello World" }); } This is the kindergarten of APIs, and that’s a good thing. What you learn here: how routing works how JSON is returned how fetch() consumes an endpoint 2. …  ( 9 min )

Awalnya aku cuma bisa HTML, CSS, dan JavaScript biasa. Saat diminta membuat proyek dengan React + TypeScript, aku benar-benar bingung. Aku mulai belajar React dari dasar: komponen, props, state, dan hooks. Semakin lama, aku mulai paham kenapa React enak dipakai—semua terasa lebih rapi dan terstruktur. Belum selesai memahami React, muncullah tantangan baru: TypeScript. Awalnya aku kesal karena error yang muncul terasa aneh. Tapi setelah terbiasa, aku sadar TypeScript justru membantuku menghindari bug. Aku belajar memberi tipe pada props, menggunakan interface, dan menulis kode yang lebih aman. Untuk melatih diri, aku bikin proyek kecil seperti Todo App dan fetch API. Dari situ aku mulai sadar pola kerjanya, dan kombinasi React + TypeScript ternyata sangat powerful. Saat akhirnya membuat dashboard untuk proyek magang, aku merasa lebih percaya diri. Struktur kode lebih rapi, error lebih mudah ditangani, dan prosesnya jauh lebih nyaman. Belajar React dan TypeScript mengajariku satu hal penting: butuh waktu untuk paham, tapi hasilnya membuat proses coding lebih cepat, aman, dan menyenangkan.  ( 6 min )

In the world of enterprise application development with Uniface, performance is king. One often underutilized but powerful feature in Uniface 10.4 is the concept of Service Stored Procedures (SSPs). If you are working with heavy data processing or complex SQL logic, moving that logic closer to the data (the DBMS) is usually the best optimization strategy. Here is a deep dive into what SSPs are, why you should use them, and the constraints you need to watch out for. In Uniface, a Service Stored Procedure isn't just a raw SQL script. It acts as a bridge. Technically, it uses the Uniface activate statement to address a Stored Procedure Component that you define within the Signature Editor. Ideally, you use these when you want to execute DBMS-specific stored procedures but maintain a generic P…  ( 8 min )

Simplifying Legacy Integration: Using Call-In Stubs in Uniface 10.4 Integration between modern 4GL environments and traditional C (3GL) code often feels like a high-wire act. You have to manually juggle memory handles, parameter mappings, and execution states. One slip—like a mismatched data type or a forgotten handle release—and your application crashes. If you are working with Uniface 10.4, there is a better way. Instead of writing verbose, error-prone C code to activate Uniface services, you can use Call-In Stubs. This feature generates clean C wrappers for your 4GL services, handling the heavy lifting automatically. Here is how to streamline your C-to-Uniface integration. Let’s say you need to call a simple operation named CALLIN inside a Uniface service CALLINSRV. Without stubs, you…  ( 8 min )

So yeah I made this fish schooling thing. Literally a bunch of fake fish vibing together on my GPU. I had nothing serious in mind. I just saw some video and my brain went ok cool lets try that. I swear half these projects I make start from boredom and ego mixed together. Like I wanna see something move on screen because it makes me feel like I actually know shit. Anyway the whole thing is just a bunch of rules. I used WebGPU and some compute shaders. Three.js for the visuals because I was too lazy to write the whole rendering thing from scratch. The logic is literally nature 101. Nothing crazy. Just looks cool. And honestly this project taught me something. People act like you need to make some god tier project every time. But nah. Sometimes you make a small thing and it still looks sexy. And it gives you that small hit of dopamine that keeps you going. When I posted it on LinkedIn I realized something sad though. If you dont hype your own shit nobody even looks at it. Like damn bro at least pretend to care. But yeah whatever. I like this one. Its small. Its stupid. It works. And watching the little dudes swim around felt kinda satisfying. If you wanna make something that looks way harder than it actually is then this is the move. Thats it.

Introducing a novel approach to global optimization, designed to efficiently navigate these treacherous landscapes without prior knowledge of the function's smoothness. The core idea is to intelligently sample the function, prioritizing evaluations that are most likely to improve our current best solution. We achieve this by adaptively refining our search region and limiting comparisons to a strategically chosen subset…  ( 7 min )

Introduction Integrating modern C/C++ applications with established Uniface systems doesn't have to be a black box. The Uniface 3GL Call-In API acts as the bridge, mirroring the power of the ProcScript activate command but from within your C code. This guide breaks down how to instantiate components and effectively manage the environment lifecycle using the ucall library. The Call-In API allows you to: Instantiate Uniface components (Forms, Services, Reports). Execute operations with full parameter support (IN/OUT). Control the Uniface environment (Start/Stop). All necessary functions are bundled in the ucall shared library. This is the single dependency you need to link against. The documentation often shows a sequence involving both creation and opening. Here is what happens unde…  ( 7 min )

I'm a software developer, and I've been attending tech events for over three years now. I've used platforms like Luma and Eventbrite to find events, but there's always been one problem that frustrated me. The noise. Most event listing sites list cool tech events, but they also mix in so many non-tech events that it becomes overwhelming. When I'm looking for a React workshop or an AI conference, I don't want to scroll through cooking classes and yoga sessions. I remember searching for "JavaScript meetups" and getting results for wine tasting events and fitness bootcamps mixed in. The problem was clear. I wanted a clean, focused experience that only showed tech events. At first, I just thought about it, but I didn't know how to approach building it.

Introduction If you work with Uniface, you know it’s a powerful low-code platform for building enterprise applications. However, there are moments when standard 4GL isn't enough. You might need high-performance algorithms, specific system calls, or integration with existing libraries. This is where the 3GL (Third-Generation Language) interface comes into play. In this post, I’ll break down how Uniface handles 3GL integration, which languages work best, and the constraints you need to know. Strictly speaking, Uniface isn't tied to a single specific 3GL language. However, because the Uniface kernel itself is largely written in C, the interface is heavily biased toward C conventions. For a language to be compatible with Uniface, it must meet three critical conditions: Calling Convention: I…  ( 8 min )

Why Softmax is Used Instead of Argmax in Neural Network Training 1. Information Loss with Argmax Argmax only returns the index of the highest logit value and completely discards all confidence information: argmax([2.1, 1.0, 0.5]) = 0 argmax([5.0, 0.1, 0.1]) = 0 Both return class 0, but we lose critical information about how confident the model is in its prediction. Softmax converts logits into a probability distribution that preserves the relative confidence across all classes: softmax(zi)=ezi∑jezj\text{softmax}(z_i) = \frac{e^{z_i}}{\sum_{j} e^{z_j}}softmax(zi​)=∑j​ezj​ezi​​ This allows the loss function to measure certainty or uncertainty, which is essential for gradient-based learning. Let's compare two scenarios with 3 classes and true label = class 0. Logits: [2.1, 1…  ( 8 min )

Introduction If you work with Uniface, you probably know that it plays well with others—specifically with 3GL languages like C or C++. We often use activate or perform to call out to legacy C libraries for complex calculations or system-level tasks. But here is the pain point: Debugging. Have you ever tried to attach a C++ debugger (like Visual Studio or GDB) to a running Uniface process? Often, the moment the debugger attaches, the application crashes or behaves unpredictably. This happens because both Uniface and the debugger try to manage the same system resources (like signals or threads). In Uniface 10.4 (specifically update 10.4.03.027), there is a feature designed to fix exactly this problem. Uniface introduced a setting called $ENABLE_USER_3GL_DEBUGGING. When this setting is enab…  ( 7 min )

Let's be honest, the traditional wall between sales and marketing teams feels like a legacy monolith with no API documentation. Marketing generates leads (pushes data to a queue), and sales complains about the quality (data validation error). The result? A leaky funnel, frustrated teams, and stalled growth. This isn't a "people problem"; it's a systems integration problem. As engineers, we solve these problems every day. We build resilient, interconnected systems. It's time to apply that same thinking to our company's revenue engine. This practice is often called "Smarketing" or, more technically, Revenue Operations (RevOps).

When working with lists in React, the go-to optimization for many developers is useMemo: const filtered = useMemo(() => tasks.filter(filter), [tasks, filter]); const sorted = useMemo(() => filtered.sort(cmp), [filtered, cmp]); This looks right, but it isn't: If you mutate the array in place, the reference doesn’t change and useMemo will return stale results. If you recreate the array every render (common in immutable flows), the memo dependency always changes and you pay the computation cost every time anyway. Hence, I built a tiny alternative — memotable (≈1.4 KB min+gz). It’s a read-friendly data structure that maintains derived views efficiently. This matters only for a narrow set of apps (typically apps that manage large in-memory datasets). Instead of the typical write-friendly pattern- const todos = new Map(); function getTodos(listId: string) { return Array.from(todos.values()) .filter((todo) => todo.listId === listId .sort(byTitle); } getTodos("list1"); // Full pass and sort on every invocation you can express the same as a read-friendly structure using memotable like- const todos = new Table(); todos.sort(byTitle); todos.index( (todo) => todo.listId, (p) => p.memo(), // Memoize list level partitions ); todos.partition("list1"); // Pre-computed list enabling fast read todos.values(); // Root partition is not-memoized and hence still sorts at read-time If your app works with thousands of items and reads are much more common than writes, memotable may be useful. As an example- based on my synthetic benchmark with R/W ratio of 4:1, memotable is ~4x faster. If you’ve hit similar problems with list-level memoization — in React or otherwise — I would love to hear about how you approached it. This is a tiny library by design, and I’m still refining where it adds the most value. Contributions, feedback or comments - all are welcome: https://github.com/shudv/memotable  ( 9 min )

Example path: /content/drive/MyDrive/DATA/iso/Win11_24H2_English_x64_Custom_Optimized.iso 4. Compute the SHA‑256 Checksum Use sha256sum (installed by default in Colab): !sha256sum /content/drive/MyDrive/DATA/iso/Win11_24H2_English_x64_Custom_Optimized.iso Output format: Compare the printed hash with the official one from the source website. They must match exactly. If not, the file may be incomplete or tampered with. File not found: Confirm the path (case sensitive). Large files: Hashing can take time; wait for completion. Different algorithm needed: Replace with !md5sum or !sha1sum (only if required; SHA‑256 is stronger).  ( 6 min )

Link to repo Sometimes I use OpenCode (and tools like Claude Code, Codex CLI, etc.) as a copy-paste backend: I prepare context in the browser, then paste it into an AI coding tool. At its core, most modern AI coding workflows boil down to two operations: Selecting the relevant context. Chatting about that selection. In my setup, a tiny browser script handles the selection: it collects and shapes the context, writes a structured payload to the clipboard, and then I paste it into OpenCode, Claude Code, Codex CLI, or any other AI coding tool just to see how it behaves - without building a real AI backend. When you hit Escape in the browser, the selection script grabs: your prompt (e.g. “Change color to red”) the current selection (code / text) some structure around it and writes a structured payload to the clipboard, like: prompt: Change color to red where:{context} ... {ADDITIONAL_PROMPT} You can try this in the browser here: https://istarkov.github.io/ai-cli-edit/ — press Cmd + E or Ctrl + E to enter editing mode and see the generated payload. Slow, higher-end reasoning models can usually consume this raw structure without extra help. Smaller or faster models often need the {ADDITIONAL_PROMPT} with more explicit instructions — for example: how to interpret … what to edit and what to keep identical formatting rules which tools to call You could dump all of this into CLAUDE.md or AGENTS.md, but those files are usually already full of generic rules and global guidelines. Better approach: keep editing-specific instructions in a separate, dedicated place. In OpenCode, this is done via Primary Agents. Create a focused file like ./.opencode/agent/edit.md that defines: your editing rules model parameters tools project-specific context (jargon, naming, edge cases, etc.) In the Claude ecosystem, the same idea appears as Skills: small, targeted capabilities that encapsulate exactly this kind of task-specific behavior.

I launched the MVP of SpeakSheet on Reddit this week. The concept is simple: You type a prompt, and my app generates a structured Excel file using Gemini. The post got 2,400 views. Most feedback was standard. But one comment stopped me cold. Is it not just a system prompt for Gemini? It is not a product... users still have to prompt. You could chat with Gemini on Google Sheets all day long and it is free. My initial reaction was defensive. But after the sting faded, I realized he was right. The "Wrapper" Fallacy But to a user who doesn't know what an API key is, raw technology is useless. They don't know how to write a system prompt to enforce column structures. SpeakSheet wraps the chaos of an LLM into a predictable, one-click interface. That is the product. The Pivot: Listening to the Haters "You could chat with Gemini on Google Sheets all day long." I realized I had missed a massive use case. Because of that "hater," I am shifting my roadmap. I am now researching Google Sheets Integration via OAuth 2.0. Building the Integration (The Plan) Authenticate the user via OAuth 2.0. Conclusion Your customers are the people who gladly pay to skip the learning curve.

The hidden order sleeps inside the chaos Something moves inside the noise before it becomes thought. Noise enters systems long before we notice it. It slips in through expectations, deadlines, abstractions, and the quiet pressure to move faster than understanding allows. This is the kind of noise that does not announce itself. It distorts direction in small, almost invisible steps. In engineering work, noise shows up as scattering. Noise creates the illusion of progress. Noise wastes energy in ways that are hard to measure. Noise pushes us into inefficiency not through chaos, but through subtle misalignment. And this is the danger: noise does not break systems by force. In this sense, noise is not the villain. This is the first half of the truth. Yet the same force that scatters us also cr…  ( 10 min )

This release follows up on release 2.08 and hopefully stabilizes the test suite even further. At the same time we are taking a first step towards the next major release by deprecating the use of XML configuration files. The preferred format for configuration files is now YAML. The XML support will be removed in a future major release, for now this is just a deprecation notice and several warnings from the test suite. When we did the last major release to version 2, see the blog post: "Major Release 2 of the Perl Distribution Workflow" We caused some grievances for one of our users, afterwards we discussed that perhaps the distribution should have been renamed to Workflow2 to better reflect the breaking changes and to make a more clear distinction and separation.

Hi everyone! 👋 If you come from the classic Client/Server world of Uniface (or any other stateful environment), moving to the web feels like losing your memory. Suddenly, your application forgets everything between two clicks. 🤯 In Uniface DSPs and Entity Services, State Management isn't just a nice-to-have—it's the backbone of your architecture. Today, let's dive into how we handle state, specifically when working with the disconnected nature of Entity Services. Let's go! 🚀 In a classic Uniface form, the database connection stays open. You lock a record, go grab a coffee ☕, come back, and the lock is still there. In the web world (Stateless), it looks like this: Load: User asks for data -> Service loads it -> Service dies. 💀 Edit: User types in the browser. Save: User clicks save…  ( 8 min )

We are currently living through the AI Gold Rush. Every day there is a new model, a new benchmark, and a new promise that AGI (Artificial General Intelligence) is just around the corner. But as developers, we have a responsibility to look under the hood. If we strip away the marketing and the VC hype, what is left? Linear algebra. A massive amount of linear algebra. The uncomfortable truth is that current AI has nothing "intelligent" about it in the biological sense. In fact, to truly replicate what nature has achieved inside your skull, we would run into a physics wall so hard it would rival a cosmic event. The first distinction we must make is between understanding and probability. Large Language Models (LLMs) do not "know" what they are saying. They are incredibly sophisticated statist…  ( 8 min )

TL;DR: I attempted to build a visual web agent using Playwright and Qwen2-VL-2B to detect and click UI elements via raw coordinate prediction. The Result: Failure. While it works on square test images, production websites on wide monitors (1920x1080) suffer from massive coordinate drift (up to 500px) due to the model's internal aspect ratio squashing. Takeaway: Raw pixel prediction is mathematically unstable for browser automation. The Dream: Imagine telling your computer, "Go to Amazon, find a waterproof Bluetooth speaker under $50, and put it in my cart," and then watching your mouse cursor move on its own, clicking and typing exactly as you would. This isn't sci-fi anymore. This is the promise of Multimodal AI Agents. But if you think building this is as easy as taking a screenshot an…  ( 11 min )

Hey fellow developers! 👋 If you’ve been working with Uniface for a while, you’ve probably heard about Entity Services (ESV). Maybe you use them daily, or maybe you're still wondering, "Why do I need this when I can just put code in my form?" 🤔 Today, let's clear up the confusion! We’re going to look at what an Entity Service actually is, why it’s your database's best friend, and how it saves you from spaghetti code. 🍝❌ Think of an Entity Service as a dedicated bodyguard for a specific database table. In a 3-tier architecture, it sits right between your business logic (like a Session Service) and the physical database. Its sole job is to handle the Data Access Logic for one single entity (table). It doesn't care about the user interface. It doesn't care about the big picture workflow. It…  ( 8 min )

Decoding the Beautiful Game: AI's Play-by-Play Revolution \Imagine trying to analyze an entire soccer match, second by second, knowing exactly who's doing what and how it impacts the overall strategy. This is the holy grail for coaches, analysts, and even broadcasters seeking to understand the nuances of every pass, tackle, and run. Now, imagine doing this automatically. This is where AI steps onto the field. At its core, we're developing a system that can automatically identify and categorize every action of every player throughout an entire game. This means not just detecting that a player kicked the ball, but who kicked it, where they were, and why – all in relation to the other players and the evolving game state. The real magic comes from integrating computer vision with an understa…  ( 7 min )

Marshaling sounds like a solved problem. json.Marshal or proto.Marshal, send the bytes across the wire, and move on with your life. But once you hit real load — tens of thousands of messages per second, strict p95 budgets, or aggressive CPU constraints — marshaling becomes one of the biggest sources of latency, garbage, and inefficiency. I didn’t believe it at first either. 20–40% of CPU time spent on serialization alone. In this final article of the series, I’ll walk through every marshaling strategy that actually matters, why it works, where it fails, and how to choose the right approach depending on your system’s requirements. Let’s get into it. 1. The Truth About Marshaling: It’s Always on the Hot Path You can usually optimize: DB queries cache lookups goroutine pools handlers …but m…  ( 10 min )

Let’s be honest: Google Chrome is that one friend who’s amazing... but eats all your food. Tabs, dev tools, web apps, YouTube, Figma — Chrome loves them all. Maybe a little too much. But here’s the good news: You can actually make Chrome faster by giving it a bigger memory allowance using a little trick called --max-old-space-size. Think of it as feeding Chrome a bigger breakfast so it stops getting cranky. Let’s break it down for Windows, macOS, and Linux. 🍳 --max-old-space-size? Chrome uses the V8 engine to run JavaScript, and V8 has a special memory area called the "Old Space" — basically the place where long-lived objects hang out. If this space is too small, Chrome panics, sweats, and starts throwing random memory tantrums (yes, garbage collection). By adding something like: --max-…  ( 7 min )

There is a dangerous assumption that 90% of Node.js developers make. They assume that if a user closes their tab, refreshes the page, or cancels an API request, the backend automatically stops processing that request. It does not. In Node.js, the HTTP layer is decoupled from your logic. If a user requests a heavy report and immediately closes the window, your server will dutifully spend the next 30 seconds crunching numbers, heating up the CPU, and running database queries, only to realize at the very last millisecond: "Oh, the socket is dead. I have nowhere to send this." This is a Zombie Request. In high-throughput systems, these zombies can consume up to 40% of your resources. Here is how to identify, track, and kill them using AbortController. You don't have to take my word for it. Cre…  ( 8 min )

I thought building across clouds would be about configuration. The goal sounded simple: create a production-ready, well-documented environment that followed best practices across AWS, Azure, and GCP. Each cloud has its own worldview. But the deeper you go, the more differences compound. Every component works, just differently. When I ran the full analysis, the data told its own story: For a senior DevOps team, that’s ~2,000+ hours of engineering time. AI compressed that into minutes. It didn’t replace us, it multiplied what we could achieve. Building a multicloud posture isn’t about running workloads everywhere. Success comes from knowing what not to replicate and what to redesign for each platform. Start building your own multicloud environment on Infracodebase and see how different clouds can tell a single, unified story. Lmk if you want me to share the full GitHub project. ❤️ Would be really happy to have a session with you to help you build your own scenario.

Remember late 2022 when ChatGPT first dropped? It feels like ancient history in tech years, but it’s barely been three years. A lot has happened since then. Back then, ChatGPT shocked the world with its eloquence and vast knowledge base. But it had one glaring limitation: it was text-only. Fast forward to today, and the landscape has shifted. With models like Gemini and GPT, it’s no longer a novelty for an AI to understand images, audio, and even video. We have officially entered the era of the Multi-Modal LLM. But how do these models actually "see" and "hear"? Let's break it down. Think of a "Modality" as a channel of communication. Text is one modality, images are another, and audio is yet another. "Multi-Modal" simply means the ability to process multiple modalities simultaneously. Huma…  ( 14 min )

Ever noticed how apps seem lightning-fast—until suddenly, one day, they’re slow, freezing, or just crashing? Most times, that’s a database problem. When you’ve got too many people using your app or your data is piling up, you need to “scale” your database so it keeps up with all that action. But how do you actually do that? Let’s break down the real-world ways pros handle this. Imagine you’ve got a big file of customer information. Some of it—like names and emails—is super important for everyday business. Other stuff, like profile pictures or bios, maybe you only check once in a while. What’s the trick? Split this huge file into two smaller tables: Main Table: name, email, last_login(the “busy street”) Aux Table: bio, profile_picture, preferences(the “quiet alley”) When most queries only…  ( 8 min )

From Weeks to 15 Minutes: How We Built a Data Migration System That Changed Everything HarshKumar Jha ・ Nov 22 #data #datamigration #technology #startup  ( 6 min )

In the last few years cybersecurity stopped being “something for big companies” and turned into a real everyday problem for small and medium businesses. Brute-force bots, phishing kits and credential stuffing tools attack thousands of websites per hour. Your business might not be “important”, but your data definitely is. One hour offline = lost sales, lost leads, damaged trust. For many companies a single day of downtime costs more than a whole year of proper security. weak passwords outdated plugins badly configured firewalls missing monitoring These are simple things, but they cause 80% of the breaches I’ve seen. Not every business can afford an in-house IT team — and that’s completely fine. What matters is to have someone who monitors your systems, reacts fast, and explains things in a simple, human way. In Bulgaria one of the teams doing this well is Network Technology — they focus on IT support, cybersecurity and infrastructure for small and mid-sized businesses. If you're looking for real-world examples, tools, or want to learn how SMEs can secure their networks, you can check them out here: 👉 https://ntg.bg/ It’s a process: monitoring, patching, checking logs, running backups, improving configurations and eliminating weak points. If you run a small online shop, office network, or any digital service — don’t wait for an incident. In 2025, cybersecurity is part of running a business, not an optional extra.

Everyone’s talking about the new 1M-token, multimodal AI wave; the real opportunity is how you turn it into revenue, speed, and defensible workflows. Google’s Gemini 3 Pro raised the bar, but the loudest demos won’t win. The edge goes to teams that ship one real workflow in 30 days. Most leaders secretly overcomplicate this and waste a quarter. Long context and multimodal isn’t just bigger memory; it’s new leverage. You can unify docs, logs, images, audio, and video into one system. I learned the simple truth: pick one painful job and wrap it with guardrails. Then design evals and feedback loops so it actually improves. Don’t chase perfect agents; chase dependable workflows with clear SLAs. Example scenario: A support team loads 500k tokens of guides and 50 hours of call audio. The agent drafts answers, links sources, and flags risk cases for human review. Handle time drops 35% in 4 weeks, CSAT rises 12 points, and reopens fall 28%. ↓ 30‑day plan that works. • Week 1 → choose one use case, define success, and set guardrails and escalation paths. • Week 2 → build the workflow, add source citations, and create a simple eval set. • Week 3 → pilot with 5-10 users, measure speed, quality, and failure modes. • Week 4 → harden, add alerts, and integrate into your main tools. ↳ Tip: If it takes more than 10 prompts to steady, the scope is too big. Do this and you transform a flashy demo into durable advantage. You’ll ship faster than rivals and learn immediately from real usage. That’s how you build moats in the new AI cycle. What’s stopping you from shipping one production multimodal workflow in the next 30 days?  ( 7 min )

It became: "If AI can do this, what's stopping it from doing my entire job?" That thought kept nagging at me. I'm a product manager, and I spend a lot of time creating the same artifacts over and over: user stories, acceptance criteria, feature breakdowns, database schemas, wireframes.

Between 1985 and 1987, a radiation therapy machine called the Therac-25 killed three people and seriously injured three others. The machine was supposed to deliver controlled doses of radiation to cancer patients. Instead, it delivered radiation doses hundreds of times higher than intended. The cause? A race condition in the C code controlling the machine. When an operator entered treatment parameters too quickly, the software would configure the machine for high-energy electron mode while the safety mechanisms thought it was in low-energy X-ray mode. The patients received massive radiation overdoses. One victim, a 33-year-old woman, felt an intense burning sensation during treatment. She died from radiation poisoning.

"I'm sorry, I don't have access to your internal repositories." Or asked it why your specific AWS bill is so high this month? "I cannot access your real-time billing data." This is the "Context Gap." Generic AI is smart, but it's blind to your work. Enter Amazon Q. Think of Amazon Q as an AI assistant that lives inside your AWS account and your IDE (VS Code / IntelliJ). It’s not just trained on the internet; it connects to your data: Your Code: It reads your private Git repos. Your AWS Environment: It knows what EC2 instances you have running. Your Docs: It can read your internal Confluence wikis and PDFs. You can install Amazon Q as a plugin i…  ( 7 min )

Based on my personal experience. But blend with a Journalist-like story to make it more interesting. Kuala Lumpur — It’s a scene familiar to many in the tech world: a young developer, lit by the glow of a laptop screen, celebrates the launch of their first simple web application. But for seasoned software engineer Ahmad (not his real name), that moment was just the first step of a decade-long journey climbing from novice coder to technical architect—a journey marked less by the mastery of CRUD (Create, Read, Update, Delete) and more by a relentless pursuit of growth and complexity. “I still remember the first time my own app let someone add and delete a note,” Ahmad recalls. “It felt like magic. CRUD opened the gate to programming for me. But I eventually realized it’s really just basic s…  ( 8 min )

The "Fun" Side of AWS 🎉 Usually, when people talk about AWS, they talk about servers, databases, and billing alarms. 😴 But recently, AWS released something completely different.

> By FlameAI Studio ⭐ Introduction Search is entering its biggest shift since the early 2000s. A new category is rising fast: AI browsers — tools like Arc Search, Perplexity, Rabbit, and Rewind that search for you instead of showing you a list of links. This is not a small UX tweak. new way of interacting with the internet. In 2025, AI browsers will become the main gateway to information — and creators, developers, and businesses must adapt now. 🔍 What Is an AI Browser? An AI browser does two things that traditional browsers don’t: 1. Searches on your behalf Instead of typing keywords → clicking links → scanning pages, 2. Understands intent, not keywords AI browsers don’t rely on exact-match terms. “Find the best free puzzle sites” “Compare cognitive models behind 16-type personality …  ( 8 min )

Stop Reinventing the Wheel 🛑 When you start building with AI on AWS, you'll realize something quickly: Everyone is trying to solve the same problems. "How do I chat with my PDF documents?"

Nine months ago I did the thing every self-hating coder does: I started a project I probably shouldn’t. Fast forward, and somehow I solo-built a production-ready social media platform called 404Nerds — a community for gamers, game designers, and anyone who loves nerd culture. I built it in Ruby on Rails (because why not, Rails is still awesome). Right now we’ve got ~15 active users posting 2–3 times a day. Not huge, but hey, for a place no one’s heard of, I’ll take it. Why am I sharing this? Part bragging rights, part looking for feedback, and part inviting you to join.

In the last blog post, I discussed a record, which is a composite data type. In this blog, I’ll talk about another composite data type: a collection. According to Oracle documentation, “A collection is an ordered group of data elements, all of the same type.” A collection is a data structure similar to a list or array in other programming languages. PL/SQL supports three types of collections: Associative arrays, Nested tables, and Varrays. Associative Arrays Nested Tables VARRAYs *single-dimensional: A PL/SQL collection always has just a single column of information in each row. *bounded and unbounded: A collection is bounded if it has predetermined limits for the number of rows. An unbounded collection has no upper or lower row limits. Let’s take a closer look at each type. Associative A…  ( 8 min )

VCs Are Betting on AI Startups, But They're Missing This Jaideep Parashar ・ Nov 23 #ai #webdev #productivity #career  ( 6 min )

VCs are throwing money at AI startups faster than any funding cycle I’ve seen in years. But here’s the part people don’t talk about: VCs are over-indexing on the wrong things and underestimating the one factor that will actually decide the next wave of winners. After watching hundreds of pitches, products, and founders trying to ride the AI wave, here’s the truth I’ve learned: VCs are betting heavily on capability, but the real leverage in AI comes from distribution + behaviour change. Let me explain what they’re missing. 1. The Market Is Overcrowded With LLM Wrappers This is the biggest blind spot.

In my experience, developers burn months writing boilerplate, chasing config drift, and IaC before a single user arrives. The market rewards velocity, not heroics. Ship slower than your competitors and your idea dies, even if it's better. Here’s what I'm doing: Use a production-grade monorepo starter that forces discipline, standardization, and speed. TurboRepo plus a unified stack. Next.js for web, NestJS for backend and Expo for native. This delivers predictable builds, consistent types, shared UI libraries, and zero-friction DX. The result: one mental model, one dependency graph, one build pipeline. This structure eliminates 80% of early-stage chaos: mismatched TypeScript configs, duplicated components, fragmented API contracts, and slow local iterations. Shared packages consolidate types, UI primitives, and business logic. You stop gluing pieces together and start building business solutions. Most developers still opt for scattered repos, mismatched stacks, and brittle hand-rolled infra. That choice kills momentum. The fastest teams centralize everything, standardize aggressively, and automate the boring work out of existence. If you want leverage, the formula is: one repo, one toolchain, one source of truth. The devs who adopt this pattern dominate velocity metrics and out-ship teams twice their size.  ( 6 min )

In enterprise environments with large data volumes, SQL queries can go from executing in seconds to taking minutes—or even hours—especially when they involve multiple tables, joins, and functions on indexed columns. In this post, I want to share a real-world experience optimizing an Oracle query that originally took far too long and how I drastically reduced its execution time by applying practical optimization techniques. It all began with a query that joined several tables across different schemas.

After reviewing the execution plan, I identified several issues: Use of functions on indexed columns (like SUBSTR()), which invalidates index us…  ( 7 min )

1. Why Streaming Output Matters Let’s start with the pain. That delay breaks immersion. Users think your app froze. Meanwhile, your front-end is hoarding tokens like a dragon hoards gold — waiting to render them all in one go. Streaming output fixes that. Instead of waiting for completion, your app receives small chunks (“token pieces”) as soon as they’re ready — like hearing someone speak word by word instead of reading their full paragraph later. It’s not about making the model faster. It’s about making the experience smoother. Technically, streaming output is incremental HTTP (or WebSocket) delivery. Token-by-token generation – LLMs don’t produce full sentences in one go; they predict tokens sequentially. Real-time pushing – each token (or short chunk) is sent back through a streaming…  ( 8 min )

The GitHub discussion has people literally saying "I just lost two hours of my day banging my head against this issue." The problem? When you click "Try it" in Mintlify's playground, every field is empty, even though your OpenAPI spec has perfectly good example values sitting right there. Your developers have to manually type or copy-paste data just to test a single endpoint. It's 2025. This is insane. So we built madrasly. Run npx madrasly your-spec.json output-dir and you get a fully interactive API playground with all fields pre-populated from your OpenAPI examples. Path parameters, query params, request bodies—everything just works. One command, zero configuration, and your developers can actually test your API without wanting to throw their laptop. Check out the live demo or grab it from GitHub. If Mintlify won't fix it, we will.  ( 6 min )

🎉 Exciting News! My project, repoal, has just launched its first version on NPM! You can install it using: npm install -g @whyang9701/repopal or run it directly with: npx @whyang9701/repopal Choosing a Name: I decided to use a scoped name for my project. This means it will be associated with my username. For example, an unscoped package like vue is just a project name and can't be reused. In contrast, a scoped package like @vue/shared is linked to the Vue organization. I went with a scoped name to avoid confusion and connect it to me. Automating the Publish Process: I used GitHub Actions to automate my publishing. GitHub has a tutorial that shows how to set this up. I modified the YAML file to trigger the publish process when I create a new git tag: name: Node.js Package on: push: tags: - 'v*' jobs: ... To update the version and push the tag, I run: npm version 1.0.0 git push && git push --tags This automation will kick in every time I update the version. Adding Provenance Statements: I also added a feature for provenance statements, which help verify where the package was built and who published it. This can enhance security. NPM provides a tutorial on how to do this. In my GitHub Actions YAML, I made two updates: Allow the runner to read the repo and use my ID token for verification: ... runs-on: ubuntu-latest permissions: contents: read id-token: write steps: ... - run: npm publish --provenance --access public Here's a green check mark that shows my publish comes with provenance statements! This check mark indicates that my package has verified information, improving supply-chain security.  ( 7 min )

From the Void to the Verified Commit There is a specific kind of magic that happens when a programmer stares at a blank page. To the uninitiated, it is just a text editor; to me, it is the void before creation. I am not merely writing algorithms; I am breathing life into a vacuum. I am building a world. The paradox of this craft is energy. I can finish a grueling day at my "regular" job, feeling the weight of the world on my shoulders, completely drained. Yet, the moment I sit down to work on my passion project, that fatigue is stripped away as if by an invisible hand. Sleep becomes obsolete. Who needs sleep when the project itself feeds you energy? The code becomes a current running through my veins. There are nights when the cognitive load becomes so immense, so crushing, that I feel m…  ( 8 min )

As an engineering manager, communicating effectively is one of your most important skills. You’re not just managing code or technical designs; you’re leading people—team members, stakeholders, and collaborators. Bad communication can lead to misunderstandings, missed deadlines, and low morale, while good communication builds trust, fosters collaboration, and drives success. Here are practical and easy-to-apply communication tips specifically for engineering managers to help you become a better leader and build stronger teams. One of the most overlooked communication skills is listening. Being a good listener means more than just hearing words; it means understanding the speaker’s emotions, intentions, and concerns. Give your full attention. Avoid distractions like phones or email during co…  ( 9 min )

AI that doesn’t assist — it works. I just built Autonomous Process Auditor (APA) for the Agentic AI Hackathon (IBM watsonx Orchestrate) — and it might be the most useful AI agent I’ve ever created. Audits suck. So I built an AI agent that does 100% of the auditing work automatically. Automates end-to-end auditing No more spreadsheets. No more human mistakes. Validates workflows across tools Slack, Jira, Notion, Gmail, internal systems — APA checks everything. Detects anomalies in real time Human reviewers catch mistakes late. AI catches them instantly. Generates audit trails automatically Every action. Every timestamp. Fully traceable & exportable. Uses IBM watsonx Orchestrate to chain skills APA can: Pull data Analyze patterns Flag issues Write reports Notify teams Log results —all without human intervention. Most “AI assistants” still need humans for everything important. Agentic AI system that completes tasks autonomously from start to finish. This is the future of work. agents that handle entire workflows. …then maybe I need to build an Autonomous Judge Auditor too 😤🔥 Would you trust an AI agent to run audits at your company?

The task is to find two numbers that sum to 0 and return their indices, given an array of integers. The boilerplate code: function findTwo(arr) { // your code here } The array is scanned through once, while keeping track of every character seen const map = new Map(); For each number x, check if -x has been seen before. If yes, return both indices. for(let i = 0; i < arr.length; i++) { const complement = -arr[i]; if(map.has(complement)) { return [map.get(complement), i]; } map.set(arr[i], i) } If no pairs sum to 0, return null. The final code function findTwo(arr) { // your code here const map = new Map(); for(let i = 0; i < arr.length; i++) { const complement = -arr[i]; if(map.has(complement)) { return [map.get(complement), i]; } map.set(arr[i], i) } return null; } That's all folks!  ( 6 min )

Summary When we think of virtual offices, we often imagine 3D spaces like Minecraft or VRChat, or 2D environments like Gather, but that's not all there is. Enter the "Light-weight Virtual Office" For example, Miro can be considered a board-type virtual office. Tools like Google Docs and Box Notes can be seen as note-type virtual offices. The lightweight virtual office pairs well with collaborative daily reports. The necessity of virtual offices is often emphasized because they offer a balanced approach between real and virtual interactions. Meeting in person can be burdensome in terms of daily life, while full remote or flexible work models may not foster enough engagement due to difficulties in gathering effectively. Virtual offices provide a good option by allowing people to "gather…  ( 9 min )

Reading time: 9 minutes PageSpeed optimization isn't new. Google released Lighthouse in 2016, and performance best practices have been documented for years. You might expect that by 2025, most professional websites would score well. The opposite is true. Modern websites are often slower than sites built five years ago. Despite faster networks and more powerful devices, the average website in 2025 is heavier, more complex, and performs worse than its predecessors. Why?

A lightweight, command-line alternative to complex ticketing systems. Using golang and cobra-cli, I built a simple command-line interface for managing support tickets. Tickets are stored locally in a CSV file. As developers, we often find ourselves juggling multiple tasks, bugs, and feature requests. While tools like Jira, Trello, or GitHub Issues are powerful, sometimes you just need something simple, fast, and local to track your daily work without leaving the terminal. That's why I built Ticket CLI—a simple command-line tool written in Go to track daily tickets and store them in a CSV file. No servers, no databases, just a binary and a text file. For this project, I choose: Go: For its speed, simplicity, and ability to compile into a single binary. Cobra: The industry standard for bui…  ( 8 min )

Over the past two years, large language models have moved from research labs to real-world products at an incredible pace. What began as a single API call quickly evolves into a distributed system touching compute, networking, storage, monitoring, and user experience. Teams soon realize that LLM engineering is not prompt engineering — it’s infrastructure engineering with new constraints. Traditional software systems are built around predictable logic and deterministic flows. LLM applications are different in four ways: Even a small prompt can require billions of GPU operations. Latency varies dramatically based on: token length (prompt + output) GPU generation batching efficiency model architecture (transformer vs. MoE) As a result, you must design for latency spikes, not averages.

🧩 The Problem When you work with microservices in AWS (especially in ECS, EKS, or internal applications inside a VPC), sooner or later you need to expose a REST endpoint through Amazon API Gateway, but without making your backend public. For many years, the only “official” way to integrate API Gateway (REST) with a private Application Load Balancer (ALB) was by placing a Network Load Balancer (NLB) in the middle. This created three common issues in real-world projects: More infrastructure than necessary (ALB + NLB just to create a bridge). Higher latency because traffic needed to make an extra hop. More cost and operational overhead: two load balancers to monitor, scale, and secure. For students or small teams, this architecture was confusing and far from intuitive: “Why do I need an NL…  ( 8 min )

I'm a senior software engineer with almost six years of experience, mostly in Rails and React. For the past several years, I've been the only engineer at my company. I've worked on teams before. I know the value of code review, of someone asking "why not just...?" before you're three layers deep in a bad abstraction. I miss that. So I'm trying to build it for myself, here. This series is called "Am I Doing This Right?" and the premise is simple: I'll walk through something I've built or a decision I've made, explain my reasoning, and invite you to weigh in. Tell me how your team does it. Tell me I'm overcomplicating it. Tell me about the footgun I haven't noticed yet. I'm not looking for validation. I'm looking for the perspective that comes from working with other engineers—something I don't get day-to-day. First up: a GitHub Actions workflow that posts to Slack with recent commits and links to SOPs whenever we deploy. It's a small thing, but it touches CI/CD, team communication, and documentation habits, so there's plenty to pick apart.  ( 6 min )

Hi lovely readers, C# 14 just arrived with .NET 10, and it brings a fun little feature that makes custom types feel even more like built in ones. You can now decide what happens when someone writes myValue++ or myValue-- on your type. This was possible before, but only with static methods that returned a new instance. C# 14 adds a new way to do it. You can now write instance operators that update the object directly. It is simple, it is clean, and it can help performance too. In this post, we are going to take a friendly look at this feature and how you can try it out. Keep in mind that you need to have .NET 1- installed in order to test this out. If you have ever created a numeric style type, you probably have used ++ to increment the number by one, or -- to decrement the number by one. N…  ( 8 min )

The MCP server functionality is built in starting from Next.js 16 and doesn't require any additional configuration in the settings files. The path to the MCP server API is /_next/mcp. Assuming your dev server is running on the port number 5002, do the following: In the .vscode folder in the root of your project, create a mcp.json file. Put the following content inside it: { "servers": { "nextjs-mcp": { "url": "http://localhost:5002/_next/mcp", "type": "http" } }, "inputs": [] } Save the file. Run your project's dev server. Open Copilot Chat. Ask something specific to Next.js, for example: nextjs devtools, are there any build errors? If prompted, allow running the MCP server and executing actions. In our case, the answer was: No Next.js devtools build errors are currently reported. Let me know if you want me to keep monitoring or run a build/test explicitly. Now let's ask what the MCP server could do for us: nextjs devtools, tell me what you are able to do? I’m connected to the Next.js devtools MCP server, so I can pull diagnostics like build/runtime errors, fetch the dev-server logs, list app/pages routes, and inspect server actions. If you need anything along those lines—checking status, seeing routes, digging into errors—just let me know which detail you want. Enjoy, and happy vibe coding!  ( 6 min )

Power BI connects smoothly to both cloud-hosted and local PostgreSQL databases once you know where to enter the right details. This guide explains the simplest possible process for connecting Power BI to: PostgreSQL hosted on Aiven, and PostgreSQL running locally on your machine All steps below match screenshot placeholders so you can insert your images exactly where they belong. Connecting Power BI to PostgreSQL on Aiven Step 1: Open Power BI and Start a Blank Report Launch Power BI Desktop. Step 2: Enter Aiven Connection Details In Aiven: Open the Aiven Console Click Services Select your PostgreSQL service View your connection information (host, port, database) Use these values in Power BI: Server: host:port Database: your Aiven PostgreSQL database name Data Connectivity Mode: Import Step 3: Enter Aiven Credentials Power BI now prompts for authentication. Use: Username: Aiven database user Password: the associated password Step 4: Choose Tables in the Navigator Power BI opens the Navigator panel. The data imports and appears in the Power BI report interface. Connecting Power BI to PostgreSQL on Localhost The process is almost identical — only the connection details change. Step 1: Open Power BI → Blank Report → Get Data → PostgreSQL Step 2: Enter Localhost Database Details Fill the fields with your local PostgreSQL configuration: Server: localhost:5432 Database: usually postgres or your custom database name Data Connectivity Mode: Import Step 3: Enter Local Credentials Typical local PostgreSQL credentials: Username: postgres Password: your local password Step 4: Select Tables → Load Choose your tables in the Navigator → click Load → Power BI imports the data. Screenshot here: Navigator showing local PostgreSQL tables. Conclusion Connecting Power BI to PostgreSQL is straightforward once you know which values to enter. Aiven uses a cloud host and port, while your local setup uses localhost. After that, both connections behave exactly the same inside Power BI.  ( 7 min )

I didn’t grow up thinking I’d ever spend this much time with a pencil in my hand. For most of my life, drawing was something I did on the edges of things—on the corners of notebooks, on scrap paper during long briefings, on whatever was around when I needed to clear my head. I never called it art. I just called it breathing room. After I retired from the Army, I didn’t expect things to hit as hard as they did. People talk about transition like it’s a door you walk through. You leave the uniform at one side, and you step into your new life on the other. But I learned real quick it’s not a door.

When we talk about software distribution, the conversation usually starts and ends with binaries. We download them, install them, and run them, and the process feels simple enough. Yet a binary that works on your system is the result of many decisions that developers and packagers quietly make behind the scenes. These decisions determine not only where the binary runs, but how its supporting files are found, resolved, and loaded. This article looks at the parts of binary distribution that developers often overlook. It explores how binaries are made globally accessible, how tools ensure the right files exist at runtime, and why these details matter more than most people think. When a binary is compiled, it contains machine instructions for a specific architecture and often for a specific op…  ( 9 min )

Loom I recently put together a small project to solve a recurring problem in my daily routine: figuring out whether the weather is actually good enough for outdoor activities like walking or biking. I noticed that looking at the temperature alone wasn’t giving me the full picture, so I built something more visual and informative. Weather affects outdoor plans in more ways than one—wind, precipitation, humidity, and even how the ground feels when you’re on wheels. I wanted a quick way to assess overall conditions without having to mentally piece together a dozen metrics from different apps. The heart of the project is a globe interface that displays weather data across different cities. Each location shows key details pulled from OpenWeather, but I also added a custom metric I call the “tire rating.” OpenWeather API → for real-time weather metrics Mapbox → for the interactive 3D globe Custom logic → for calculating the tire rating In the video, I walk through how to set everything up with your own API keys so you can experiment with it locally or build on top of it. The tool is still evolving, and there’s plenty of room for creative extensions—notifications, historical comparisons, activity presets, or even AI-powered suggestions. I’d love to hear your thoughts! If you try it out or have ideas for improvements, feel free to share. Your feedback can help shape the next version. Tool: https://weathertier.lovable.app/  ( 7 min )

Finding a job as a developer has become both easier and more challenging at the same time. Easier because companies everywhere now rely on software, which creates constant demand. Challenging because expectations have risen and the hiring process has grown more complex.

AI coding has moved from a futuristic idea to an everyday tool that quietly reshapes how developers work. What once felt like a fantasy, the idea of a machine understanding code and writing it almost like a human, has become a practical reality in just a few years. The change did not happen overnight. It grew from a long journey of research, experimentation, and the ambition to make programming more accessible and more powerful. The story begins with early attempts to teach computers how to understand patterns in text. At first, these systems could only autocomplete a few words in a predictable way.

Building a Production-Ready NLP System That Traders Actually Trust A trader approaches you with a question: "Your model says this stock is bearish based on the news. But why? What words triggered that prediction?" You pause. Your 86% accurate sentiment classifier suddenly feels useless because you can't explain it. This is the hidden crisis in financial AI. Accuracy without explainability is a liability, not an asset. I learned this the hard way while building a financial sentiment analysis system for Lloyds, IAG, and Vodafone. The project forced me to solve a problem that most data scientists ignore until it's too late: how do you make a black-box NLP model trustworthy enough for high-stakes trading decisions? When I started, the goal seemed straightforward: build a sentiment classifier t…  ( 10 min )

Unlock the Power of Lookalike Modeling in Advertisements As a seasoned ML practitioner, you're likely familiar with the concept of lookalike audiences. However, have you considered leveraging this approach to optimize your ad spend and improve campaign performance? Here's a practical tip on how to do it: Identify High-Value Lookalikes Using Recurrent Neural Networks (RNNs) When targeting online ad campaigns, it's essential to identify high-value lookalikes with similar characteristics as your existing customer base. This requires a deep understanding of the complex interactions between different features and user behaviors. To solve this challenge, you can develop a custom RNN model that takes into account both structured (e.g., age, location, interests) and unstructured data (e.g., user behavior, device usage). Train your RNN model on a large dataset of user interactions, and tune its hyperparameters to capture the intricate patterns and relationships between these features. Actionable Steps: Data Preparation: Collect and preprocess a comprehensive dataset of user interactions, including features like demographics, behavior, and device usage. Model Development: Implement a custom RNN model with optimized hyperparameters to capture complex relationships between features. Lookalike Modeling: Input user attributes into the RNN model and generate a predicted lookalike score, indicating the likelihood of a user matching your target audience. Ad Campaign Optimization: Leverage the lookalike score to create high-value targeting audiences, optimizing your ad spend and improving campaign performance. By incorporating this advanced RNN-based approach to lookalike modeling, you'll be able to identify high-value targets more effectively, driving more conversions and revenue for your advertising campaigns.

This component was built as a small experiment in combining a complete game-tree search with a reactive user interface. Tic-tac-toe is simple enough that every possible board state can be explored, so the minimax algorithm fits naturally. The intention was to keep the logic straightforward and self-contained, while letting LemonadeJS handle UI updates without additional abstractions or complex lifecycle handling. I have chosen to keep minimax free of shared mutable state and avoid mutating the board during evaluation. Many examples modify the board in place and then undo moves later, but this easily introduces subtle bugs, especially once each cell starts holding more properties. Since the tic-tac-toe board is only nine cells, cloning before each simulated move is cheap and keeps each bran…  ( 9 min )

Network traffic analysis is a superpower. Whether you are debugging a distributed system, reverse-engineering a legacy protocol, or performing security auditing, you usually end up opening Wireshark. But what if you want to automate that detection? What if you need to trigger a specific action the moment a specific text sequence—like a specific username, a specialized API key, or a magic header—hits the network card? Writing a kernel-level driver to capture packets is painful and dangerous (one bug = Blue Screen of Death). Using raw socket libraries (like libpcap) is powerful but can be a nightmare regarding cross-platform compilation (Windows headers vs. Linux headers). In this article, I’ll explain how I built a Rust-based CLI tool that wraps the power of TShark (Wireshark) to monitor li…  ( 11 min )

Intro VolBack? UT). Imagine we have a CRM, which has a lifetime of 3 days. Day 1. We added 100 mb Day 2. We added 50 mb Day 3. We added 30 mb What does it mean? Backup for day 1: 100 mb Backup for day 2: 100 mb + 50 mb =150 MB Backup for day 3: 150 mb + 30 mb =180 MB Nice! So the total backup volume will be: 100 mb + 150 mb + 180 mb =430 MB. To handle this calculations I find a mathematical formula for this process. Sn=n⋅x1+∑i=1n−1(n−i)∗ai S_n = n \cdot x_1 + \sum_{i=1}^{n-1} (n - i) * a_i Sn​=n⋅x1​+∑i=1n−1​(n−i)∗ai​ Where: n: quantity of UT (second, hour, day, etc) x1x_1 x1​ : initial value of volume at first UT a: array of a values (additions in volume at each IT) Development I will expand this method in case when we don't now additions' values.

In the previous article, we solved the issue of loading static resources (like images) within Markdown. Up to this point, our documentation pages can display content, code highlighting, and images nicely. However, readers still face difficulties navigating the documentation. The pages are isolated islands: without manually typing the URL, you cannot jump from one article to another. Documentation sites like Docusaurus typically use a "Left Sidebar + Right Content" layout. In this article, we will implement this feature: we will write a function to automatically scan all Markdown files in the docs/ directory, extract their titles, and dynamically generate a sidebar navigation menu. First, we need to change the page layout from the original "single-column vertical structure" to a "two-column…  ( 10 min )

When working with Terraform, you may run into this GitHub error: This error is common among Terraform beginners and even experienced engineers because of how Terraform organizes provider binaries. GitHub rejects any file larger than 100MB, and Terraform providers typically weigh between 200MB–500MB. In this article, I’ll walk you through exactly why it happens, how I fixed it, and how you can prevent it from ever happening again. Terraform downloads provider binaries into: .terraform/ If you run: git add . before adding .terraform to .gitignore, Git starts tracking these massive files. Even if you delete the folder later, the large files remain in your Git history, and GitHub scans the entire history during a push. Then: git add .gitignore git commit -m "Add Terraform ignores files" Even after ignoring, GitHub still rejects the push because the massive files are stored in old commits. To fix this, we use a powerful tool: git-filter-repo. git filter-repo is a powerful and versatile tool for rewriting Git repository history. It is a Python script designed to be a faster, more capable, and more user-friendly alternative to git filter-branch To install the git filter-repo on my machine (wsl on windows) I used the following commands sudo apt update sudo apt install git-filter-repo run: git filter-repo --version Then clean your history: git filter-repo --force --path .terraform/ --invert-paths This removes all .terraform files from all past commits. The commit history has changed, you need to force push to upload the cleaned repository to Github without the large files git push --force This takes care of the large file error. Never commit: .terraform/ terraform.tfstate terraform.tfstate.backup provider binaries This error is very common for Terraform beginners and even experienced engineers. Ignore .terraform Clean the Git history with git filter-repo Force-push the cleaned repository Taking the time to clean your repo ensures you maintain a lightweight, secure, and professional Terraform project.  ( 7 min )

The Problem When managing events, it's common to encounter a rapid succession of events within a brief period. For instance, within an application driven by events, creating an entity can trigger multiple events like EntityAdded, EntityChanged, SubEntityAdded, etc. However, if the primary objective is to monitor changes in a specific entity item, processing all these events to dispatch a notification or outbound message to downstream systems might be unnecessary. Based on the problem described above, we are often interested in only knowing that an update has occurred at a certain moment, rather than communicating every single change. This can be effectively managed within a short predefined timeframe, typically 5 to 10 seconds. This pattern is particularly common when dealing with primar…  ( 7 min )

If you’re reading this, you likely know your way around interface, type, and generics. You probably have strict mode enabled. But TypeScript is capable of much more than just catching typos or ensuring a prop exists.

Sometimes, you even have to abuse the type system to get the safety you really want. Here are 7 patterns—ranging from modern best practices to "dark arts" hacks—to elevate your TypeScript mastery. satisfies Operator Introduced in TypeScript 4.9, satisfies is a game-changer.

It isn’t. Google well Stop chasing languages. Start building the mindset. 🎯 2. Define Your WHAT and WHY Before choosing a language or tutorial, ask yourself: What do you want to build? This decides your path. Websites → HTML + CSS + JavaScript Most beginners skip this step — and get lost. 🧩 3. Pick Your First Language (Without Overthinking) There’s no “best” language. There’s only the best for your goal. Pick one, stick to it for a few months, and ignore everything else. 📚 4. _ Use High-Quality Resources (and Avoid Tutorial Hell)_ Tutorials are great… until you watch 40 hours and still can’t build a simple project. FreeCodeCamp That’s where real skills form. 🛠 5. Project-Based Learning (Your Cheat Code) You don’t level up by watching tutorials. Start small: Example: Built a calculator? Add scientific functions. This transforms you from “learner” to “creator.” 🤝 6. Share & Collaborate (The Fastest Way to Grow) You learn faster when others see your work. Post your progress on: DEV.to You’ll get feedback, new ideas, and motivation from others building alongside you. You don’t need to be perfect — you just need to show up. 💡 Bonus: Great Project Repositories These two GitHub repos can keep you busy for months: Build Your Own X — recreate famous tools Learn X by Doing Y — Project-based guides for every tech Endless inspiration for projects. 🔥 Final Thoughts Learning to code effectively is simple: Know what you want to build Pick one language There is no perfect path.

After helping folks build MVPs out of their napkin sketches, I keep coming back to Django + Tailwind + Cursor AI. Here's why this combo works so well for getting products to market quickly. Django gives you everything out of the box. Authentication, admin panel, ORM, form handling, security features - it's all there. While other frameworks make you piece together solutions, Django lets you focus on building your actual product. For early-stage startups burning through runway, this matters. Tailwind keeps the frontend moving fast. No context switching between HTML and CSS files. No fighting with Bootstrap's opinions. You style components right in your templates and move on. The utility-first approach means you're not spending hours naming CSS classes or organizing stylesheets. Cursor AI accelerates everything. Honestly, this has been a game-changer. Need to generate a Django model with all the right field types? Cursor writes it. Building a form with validation? Done in seconds. It understands Django conventions and Tailwind classes, so you're not just getting generic code - you're getting code that fits your stack. What used to take hours now takes minutes. Obvioiusly, you will need to have a half way decent understanding of what its doing - else it might take you for a ride ever so often. The combination just flows. Django templates + Tailwind utilities + AI assistance = unprecedented speed. Need a dashboard? Build it in a day. User authentication flow? Done by lunch. Cursor handles the boilerplate while you focus on business logic. If you're sitting on a product idea or helping someone build theirs, this stack removes so many obstacles. You spend time solving business problems, not framework problems. What's your preferred stack for rapid development? Are you using AI coding tools yet?  ( 7 min )

The gap between what AI companies promise and what actually exists is widening. The AI industry is advancing faster than any technology wave of the last four decades. But speed isn’t the real issue. The real issue is the growing distance between public narratives and ground truth. Today, the loudest voices in AI—major companies, founders, VCs, and influencers—shape expectations that don’t match the systems being built, tested, or deployed. If you’re a developer, founder, or tech professional, this truth gap impacts how you learn, what you build, and how you make decisions. Here is how I see the problem. Every week a new model is introduced as: “AGI-level” “100x faster” “Better than humans” Yet in real-world use, the shine fades quickly.

Ghost-Note’s Tiny Desk concert is a straight-up funk explosion led by founders Robert “Sput” Searight and Nate Werth (both from Snarky Puppy). The duo-turned-supergroup kicks off with punchy James Brown–meets–Sly & the Family Stone grooves on “JB’s Out” and “Move with a Purpose,” then slips into a spacey, R&B–tinged “Synesthesia” before revving back up for the James Brown tribute “Be Somebody.” They wrap things with the soulful love story “Slim Goodie,” complete with Werth and Searight trading rapid-fire percussion solos and Mackenzie Green’s pleading vocals that’ll have you wishing for your own Slim Goodie. It’s a tight, electrifying set that proves Ghost-Note still knows how to make every face break into that signature funk “stank position.” Watch on YouTube  ( 6 min )

Part 1: The Business Story – Why We Built This The Problem Nobody Talks About Imagine this: It's Monday morning at a utility company. They've just signed up for SMART360—an amazing platform that will transform how they manage customers, meters, and billing. They're excited. Their leadership is excited. Then reality hits. They have 500,000+ customer records sitting in an old system. They need to move it all over. The spreadsheets are messy. Column names don't match. Phone numbers are formatted differently. Some data is missing. Some is duplicated. Their options? Manual mapping: Hire a team to manually match columns, clean data, and load it in batches. Timeline? 4-6 weeks. Cost? Thousands in labor.

Understanding authentication and authorization is essential for any backend, frontend, or full-stack developer. These two security concepts sound similar, but they solve completely different problems. Let’s break them down in a simple, beginner-friendly way. Authentication: Who Are You? It usually involve: Providing a username/email Providing a password Once the system knows who you are, it must decide: Which endpoints you can access. What actions you can perform. Which resources you are allowed to modify. Example: *Examples of Authentication Methods Bearer Token Authentication A Bearer Token is a random string given to a user after they successfully log in.You store the token (usually in localStorage) and send it on future requests. How it works: You enter your email + passwo…  ( 7 min )

Introduction Modern SaaS commerce platforms often face a similar challenge: supporting a large number of customer-specific storefronts, each with its own custom domain, while still relying on a shared backend. When your infrastructure is built on EKS with CloudFront and an Application Load Balancer in front, and each tenant requires its own SSL certificate, scaling becomes a real architectural puzzle. This article describes the problem we encountered, the options we evaluated, and the architecture we ultimately implemented to handle hundreds of HTTPS-enabled custom domains cleanly and reliably. Our platform allows customers to create online shops under their own domains. Dozens or even hundreds of domains like: storeABC.com, brandshop.net, or my-boutique.co.uk — all point to a shared Cl…  ( 9 min )

Introduction: Why i said yes to the unknown I stumbled upon this challenge while browsing developer communities online, and honestly, my first instinct was to scroll past it. The challenge was clear: build a flash loan program on Solana using Anchor framework. Simple enough on paper, but there was one problem —I had never touched Solana development before. The requirements were intimidating: Rust: A language I'd love to still learn but currently don't know much about Anchor Framework: Completely new territory Solana's programming model: Foreign concepts like PDAs, instruction introspection, and BPF programs By all reasonable measures, I should have skipped it.

Every developer has their little rituals — the way they arrange their windows, the shortcuts they swear by, the terminal theme that somehow makes debugging less painful. For me, those habits live inside my dotfiles. Over time, they’ve become more than just configs. They’re like a memory of how I prefer to work. And whenever I set up a new machine, applying my dotfiles feels like unpacking my own desk: suddenly everything is familiar again. So here’s a human-friendly walkthrough of the things I actually use from my dotfiles repo: https://github.com/rubiin/dotfiles Chezmoi: My quiet helper Before I used chezmoi, setting up my environment after a fresh install felt like trying to remember a dream — “What alias did I use again?

You're writing clean code, filling arrays efficiently, but there's a hidden performance trap that catches even experienced developers: filling arrays in reverse order. Let me show you why this innocent-looking pattern can tank your app's performance and how to avoid it. Consider these two seemingly equivalent approaches: // Approach A: Forward filling const forwardArray = []; for (let i = 0; i = 0; i--) { reverseArray[i] = i * 2; } Both create identical arrays, right? Wrong. The second approach can be significantly slower and use more memory. Here's why. JavaScript engines like V8 (Chrome, Node.js) and SpiderMonkey (Firefox) are incredibly smart.

The Challenge We Face How do you teach event-driven architecture to 8-year-olds? The answer: Scratch's broadcast messages. After teaching 50+ students, I've found broadcasts are the breakthrough concept that transforms beginners into real programmers. Students see immediate results. When they broadcast "explosion," sprites react visibly—no abstract console logs to decipher. Message names like player_jumped and level_complete are self-documenting. Compare this to: document.addEventListener('click', handleClick) Start simple: broadcast [start] When I receive [start] → show Progress naturally to state machines and event queues. Here's the secret: students are learning real software architecture. Scratch: broadcast [button_clicked] When I receive [button_clicked] → handle click JavaScript…  ( 7 min )

Amazon Linux changed its package manager from yum to DNF starting with Amazon Linux 2023 (AL2023). The main motivation for this change was to adopt the more modern, efficient, and secure package manager that DNF provides, which is now the standard across most Red Hat-based distributions. DNF (Dandified YUM) is the successor to yum and offers major improvements: Faster and more reliable dependency resolution, thanks to a new dependency solver and persistent metadata cache. Improved performance and lower system resource usage compared to yum. Enhanced support for parallel operations, extension/plugin development, and delta RPMs for better update efficiency. A stricter and more predictable API, facilitating the development of automation and third-party integrations. More robust security and better memory management. Aligning with industry standards, as DNF had already replaced yum as the default in Fedora (since version 22), CentOS (version 8+), Rocky Linux, and RHEL 8+. The transition occurred with the release of Amazon Linux 2023 (AL2023). Earlier releases, like Amazon Linux 2 (AL2), used yum as the default package manager. From AL2023 onward, all yum-like commands should be executed using dnf. The commands remain almost identical, ensuring backward compatibility for users transitioning from yum to dnf. Summary Table: Amazon Linux Package Manager Evolution Version Package Manager Reason for Switch First Released Amazon Linux 2 yum Older, less efficient dependency handling 2017 Amazon Linux 2023 dnf Modern, faster, secure, aligns with RHEL 2022 Every major Red Hat-based Linux distribution has shifted to DNF for improved reliability, performance, and future compatibility, making it the logical default for Amazon Linux going forward.  ( 7 min )

In previous articles, I talked about how I generate tests using LLMs, parse Swagger schemas, and fight against hardcoded data. But "naked" LLM generation has a fundamental problem: it is linear. The model often tries to guess the next step without understanding the big picture. Yesterday, I deployed the biggest architectural update since I started development — the System of Planning and Reasoning. Now, Debuggo doesn't just "write code." It acts like a Senior QA: first, it analyzes requirements, assesses risks, decomposes the task into subtasks, and only then begins to act. I want to show you "under the hood" how this works and, most importantly, honestly compare: did it actually get faster? The Problem: Why Does AI Get Lost?

Ghost-Note’s Tiny Desk concert kicked off with Robert “Sput” Searight’s trademark “buckle up,” and never let go. The supergroup—born in 2015 as a drum-and-percussion duo by Searight and Nate Werth (of Snarky Puppy fame)—laid down gritty funk in tracks like “JB’s Out” and “Move with a Purpose,” complete with tight call-and-response riffs and bubbling harmonies. Dominique Xavier Taplin’s spacey keys paved the way for Mackenzie Green’s sultry “Synesthesia,” and Searight amped the energy even higher on “Be Somebody,” a loving nod to James Brown. They wrapped things on a high note with “Slim Goodie,” a playful love story that features fiery percussion solos from Werth and Searight and Mackenzie Green’s pleading vocals that leave you craving your own Slim Goodie. With a full lineup of drums, horns, guitar, bass, keys, and vocals, Ghost-Note proved their evolution from a duo into a full-on funk powerhouse. Watch on YouTube  ( 6 min )

Introduction I have been meaning to try out AI-assisted coding for quite some time. Now don't get me wrong, I have been using the generic LLM chatbots. While I was able to get things done, it wasn't the best experience as a developer. I felt more and more sidelined by the process. And after a while I started picking the path of least resistance, i.e. vibe coding. And it's not just me, many of my colleagues are going through this as well. I feel that there has to be some middle ground where a coder can utilise AI all the while improving on his skills. In this article I will be exploring Kiro, an AI assistant by Amazon that uses Claude under the hood. I am specifically interested in the spec-driven development. While I do sound like a Kiro advert at this point, but come on man, they gave a…  ( 9 min )

Introduction: The Zero Balance Revolution In 2025, Indian banking has transformed dramatically. The burden of maintaining minimum balances and facing penalties for non-maintenance is becoming a relic of the past for informed consumers. Zero balance savings accounts do not charge any penalties on zero balance and come with multiple benefits for the accountholders. However, there's a critical distinction most guides overlook: Not all zero balance accounts are created equal. Many banks promote BSBDA (Basic Savings Bank Deposit Account) under schemes like Pradhan Mantri Jan Dhan Yojana, but these come with significant limitations—typically only 4 withdrawals per month, no chequebooks, and restricted digital access.

Series: OSI Layer-Based Security (Part 4) At Layer 4—the Transport Layer—we leave behind maps and arrive at conversations. This is where TCP handshakes negotiate reliability, where UDP broadcasts scatter unconfirmed messages, and where ports serve as numbered doorways to services. Layer 4 transforms routing into dialogue. But dialogues can be hijacked. Handshakes can be abandoned mid-greeting. Doors can be knocked upon endlessly without purpose. Attackers exploit this layer to exhaust resources, steal sessions, terminate connections, and probe for vulnerabilities. In this article, we'll examine the major threats at Layer 4, then compress them into timestamped resolutions—glyphs of refusal that protect the integrity of network dialogue.

Introduction While developing a Socket Chatting program, I encountered a question: how should I handle messages that exceed the predefined buffer size? // Client send(sock, packet1, 10, 0); // Send 10 bytes send(sock, packet2, 20, 0); // Send 20 bytes // Server char buffer[1024]; int bytes = recv(sock, buffer, 1024, 0); What will the value of bytes be? 10? 20? "We can't know." The size of data received from the client is unpredictable. recv() can: Receive all 30 bytes at once Receive 10 bytes and 20 bytes separately Split into 15 bytes twice Even split into 7 bytes, 13 bytes, and 10 bytes This is called the Packet Boundary Problem. Unlike UDP, TCP transmits data in byte units rather than message units. send(sock, "Hello", 5, 0); send(sock, "World", 5, 0); When a client sends a 5-byt…  ( 8 min )

Hey developers! 👋 I've been working on a side project for the past few weeks, and I'm excited to finally share it with you all. TL;DR: I built PokeSuite, an all-in-one Pokémon toolkit that focuses on UI/UX and satisfying animations instead of just static text lists. 🚀 I just launched on Product Hunt today! If you like the project, I'd really appreciate your support: 👉 Support PokeSuite on Product Hunt As a long-time Pokémon fan, I noticed that most "randomizers" or "team generators" out there are functionally great but look like spreadsheets from 2005. I wanted to build something that felt like a modern web app—responsive, dark mode by default, and interactive. I built this using the modern React ecosystem. Here is what's under the hood: Framework: Next.js 14 (App Router) – For SEO and performance. Styling: Tailwind CSS – Made building the dark mode UI incredibly fast. Data Source: PokeAPI – The holy grail for Pokémon data. State Management: React Context + LocalStorage (No login required for users). Deployment: Vercel – Zero-config deployment. TCG Pack Simulator: This was the fun part. I used CSS animations to mimic the feeling of ripping open a booster pack. Competitive Team Builder: It includes filters for VGC and Smogon tiers (OU/UU), which required some complex data filtering logic. Spinning Wheel: A physics-based wheel to pick random Pokémon. The hardest part was handling the massive amount of data from PokeAPI without slowing down the UI. I had to implement efficient caching strategies and optimize the images to ensure the "Pack Opening" animation remained smooth on mobile devices. It is completely free, open to everyone, and requires no sign-up.

How can we be sure we've covered all the tricky edge cases and interactions between different inputs? Manually writing these tests is tedious, and a simple brute-force approach can lead to a combinatorial explosion of test cases. This is where a smarter approach, like using a Genetic Algorithm (GA), can be a game-changer. In this article, I'll walk through a project that uses a GA to automatically generate a concise and effective set of test cases for a complex e-commerce pricing function, explaining the core logic step-by-step. To demonstrate the power of the GA, we need a sufficiently complex function. In my experiment, I used a Python function that calculates the final pr…  ( 9 min )

A technical perspective on decentralized national compute architecture Chapter 1 — Nations Depend on Compute More Than Ever Modern governance increasingly depends on large-scale computation to: run national identity systems power public services & AI citizen portals store medical records and civil registries support defense analytics and threat modeling process massive research workloads Historically, governments have sourced most of this compute from corporate cloud providers such as AWS, Google Cloud, Azure, and Oracle. This creates a structural dependence: National infrastructure often runs on servers not owned, operated, or located within the nation itself. While centralized clouds provide performance and reliability, they also raise questions around: sovereignty cost s…  ( 8 min )

Today, whatever is new quickly becomes old. We started with AI, then moved to Generative AI, and now it’s Agentic AI. Honestly, the lines blur because everything overlaps and shines depending on our use cases and requirements. Before diving deeper, it’s also key to clarify the difference between Generative AI and Agentic AI. Generative AI is reactive; it creates content—text, images, code—based on user prompts. It focuses on what to create when asked. In contrast, Agentic AI is proactive and autonomous. It takes initiative, sets goals, plans multi-step workflows, makes decisions, adapts dynamically, and executes tasks with minimum supervision. Generative AI powers content within these systems, but Agentic AI orchestrates entire processes to achieve goals efficiently, turning AI from …  ( 8 min )

Exploring Backend Development with Rust and Go: Insights from Web Developer Travis McCracken As a passionate Web Developer, I’ve always been fascinated by the evolving landscape of backend development.

I am building a Micro-SaaS called SpeakSheet. The premise is simple: You speak (or type) a prompt, and it generates a structured Excel file. The stack is solid: NextJS, Tailwind, Supabase, and Gemini on the backend. This week, I tackled the hardest part of the MVP: Formulas. Teaching an LLM to understand "Profit Margin" is tricky. It knows the math, but it doesn't know the context. After hours of tweaking the JSON schema and refining the prompt, I finally got a green light in the console. The logic was perfect. The schema was validated. I downloaded the generated file to test it. Profit Margin: 0. I stared at the screen. I felt that specific mix of confusion and anger that only developers know. I checked the backend logs—the calculation was correct. I checked the cell data—the formula was there. But the cell displayed 0. I spent an hour debugging a bug that didn't exist. The Invisible Villain Protected View: Be careful—files from the Internet can contain viruses. Because my software generated the file programmatically, Excel didn't trust it. It blocked the execution. I realized that for a user with low Excel literacy (my target audience), this is a dealbreaker. They won't click "Enable Editing." They will just churn. I had to refactor the user journey to account for a security feature I have no control over. The Design Pivot (feat. Gemini 3.0) I am a developer, not a designer. Usually, this is where I stall. I decided to test Gemini 3.0 Flash. I gave it a simple instruction: Design a modern, clean landing page for a SaaS that converts text to Excel. I expected the usual generic AI slop. It saved me two days of CSS wrestling. The Lesson Your logic can be perfect, but if Excel's UI hides it, you failed.

HTML can feel like a long list of tags until you notice the quiet architecture hiding underneath. Browsers aren’t tossing those tags around at random, they’re following a predictable pattern that gives every page its skeleton. Once you understand that structure, the rest of HTML clicks into place. Suddenly you’re not memorizing, you’re navigating. At the center of it all is the document itself, the recipe the browser reads from top to bottom. It starts with a declaration, moves into a root, then steps through a head before finally reaching the body. These aren’t just sections of a file; they’re roles in a performance. The browser is the actor. Your markup is the script. Here’s a quick refresher on the boilerplate HTML layout: <meta charset="UTF…  ( 7 min )

Your company blog is live. It’s got a product update from last quarter, a post about the company picnic, and a generic "5 Ways to Improve X" article. The traffic graph is flatter than a minified CSS file. Sound familiar? Most B2B company blogs are treated like a chore—a digital ghost town of forgotten press releases and shallow content. But what if you treated your blog like you treat your product? What if you engineered it, not just to exist, but to establish your company as a genuine thought leader in your space? Let’s refactor our approach. This isn't about content marketing hacks; it's about building a system to consistently output high-signal, high-value content that developers and engineers actually want to read.

The notification appears at 3:47 AM: an AI agent has just approved a £2.3 million procurement decision whilst its human supervisor slept. The system identified an urgent supply chain disruption, cross-referenced vendor capabilities, negotiated terms, and executed contracts—all without human intervention. By morning, the crisis is resolved, but a new question emerges: who bears responsibility for this decision? As AI agents evolve from simple tools into autonomous decision-makers, the traditional boundaries of workplace accountability are dissolving, forcing us to confront fundamental questions about responsibility, oversight, and the nature of professional judgment itself. The transformation of AI from passive tool to active agent represents one of the most significant shifts in workplace …  ( 20 min )

As businesses continue to deliver seamless digital experiences, the way we test applications has become more critical than ever. “web app testing” and “mobile app testing” at the start in this way to improve keyword relevance and make the introduction easier to read. To ensure consistent quality, QA teams must adapt their strategies depending on whether they’re testing a mobile app or a web app. The differences go far beyond screen size-ranging from device fragmentation and operating system diversity to installation flows, hardware integration, and even network variability. These challenges mean that the same QA approach cannot be applied to both environments without risking missed bugs or poor user experiences. If you’re interested in a foundational understanding of QA practices, check out our earlier blog on Everything You Need to Know About Functional Testing: A Beginner’s Guide In this blog, we’ll explore the key differences between mobile and web app testing, including device and OS diversity, installation and release processes, UI responsiveness, hardware-specific testing, performance constraints, and network considerations. We’ll also cover practical insights into build distribution, release workflows, and do’s and don’ts to help QA engineers deliver more reliable applications across platforms.

New vitamin D research and what it means for your health Vitamin D helps the body absorb calcium and supports bone health. Recent studies revisit its wider roles, including immune and cardiovascular health. However, the evidence for supplements remains mixed. The standard test measures 25-hydroxycholecalciferol or 25(OH)D blood levels. A deficiency is below 30 nanomoles per liter. Because most vitamin D comes from sunlight, skin exposure drives levels. In addition, diet provides oily fish, egg yolks, mushrooms, and fortified foods. Infants need supplements at least until age one to prevent rickets. Low vitamin D associates with higher blood pressure and greater cardiovascular event risk. However, trials give conflicting results about whether supplements reduce these risks.

In the world of TypeScript, modules play a crucial role in organizing and structuring code for better maintainability and scalability. Let's dive into the world of modules in TypeScript and explore how they can enhance your development experience. Modules in TypeScript allow you to divide your code into reusable components that can be easily imported and exported across different files. This helps in keeping your codebase clean and organized. To export a module in TypeScript, you can use the export keyword followed by the element you want to export. For example: // mathFunctions.ts export function add(a: number, b: number): number { return a + b; } You can then import this module in another file using the import statement: // app.ts import { add } from './mathFunctions'; console.log(add(2, 3)); // Output: 5 In addition to named exports, TypeScript also supports default exports. You can export a default module like this: // logger.ts export default function log(message: string): void { console.log(message); } And import it using: // app.ts import log from './logger'; log('Hello, World!'); By using modules effectively, you can organize your codebase into logical units, making it easier to maintain and scale. You can create separate modules for different functionalities such as authentication, data manipulation, and UI components. TypeScript uses a system called 'module resolution' to find and load modules in your code. There are different strategies for module resolution, such as Node.js style, Classic, and others. Understanding how module resolution works can help you avoid common pitfalls when working with modules. Modules are a powerful feature in TypeScript that can greatly improve the structure and organization of your code. By mastering modules, you can write more maintainable and scalable applications. Start leveraging the power of modules in TypeScript today!  ( 7 min )

Real estate has traditionally been one of the most stable and lucrative investment classes. However, unlocking the true value of property has often been limited by high capital requirements, complex legal processes, and illiquid markets. Many valuable properties remain underutilized because their owners cannot access sufficient liquidity, and investors are unable to participate due to entry barriers. Real estate tokenization—a blockchain-driven innovation—is rapidly changing this landscape. By converting ownership of a property into digital tokens, property owners and developers can unlock capital, enhance liquidity, and expand access to a broader investor base, fundamentally redefining how property value is realized. Tokenization enables fractional ownership, automated management of incom…  ( 10 min )

1. What is JOLT? JOLT (JSON-to-JSON Transformation) is an open-source Java library (originally from Bazel/Spotify) used to: ✔ Transform JSON into a different JSON JOLT uses a transformation spec, written as JSON, to tell how input JSON should be transformed. 2. Why and When to Use JOLT? Use JOLT when: Examples: Backend receives API JSON and needs to convert it to another JSON format. Integrating with 3rd-party APIs that return weird JSON structure. Without JOLT you'd write dozens of lines of ObjectMapper, maps, loops, etc. JOLT reduces this to a tiny JSON transformation spec. You can store the spec in: a file, a database, config properties, or generate dynamically. 3. What is a Spec? A spec is a JSON array describing transformation steps.

I’ve been doing web development for roughly 15 years. I remember the days before npm, the rise of jQuery, Bootstrap, the explosion of SPAs, and things in between. I’ve seen exciting trends and helpful tools, but lately, I’ve also seen frameworks that are increasingly confusing. Today's web development seems to be heading in an uneasy direction. We have normalized a level of complexity that pulls developers away from the basics of the web and into a walled garden framed by build tools, transpilers, and packers. I’m lucky to be self-employed, which gives me a unique perspective. I don't have a boss or a job description forcing me to use a specific framework, and that gives me the freedom to build my own way.

TLDR: badtrace on GitHub I needed a tool that would deliberately generate OpenTelemetry traces that were "bad". I needed this for training, enablement and demo purposes so that I could easily fire a trace with a known issue into my Observability system and thus show "why it was bad" and "how it looks". Yes, tools like tracepusher and telemetrygen already exist, but they typically: a) Generate "good" or "healthy" traces Hence, "badtrace" was born. It works based on "scenarios" (you can implement your own in a few lines of Python). python app.py \ --endpoint=http://localhost:4318 \ --service-name=badtrace \ # optional: defaults to "badtrace" --trace-count=1 \ # optional: defaults to 1 --insecure=true \ --scenario=scenario1 As I write this, there are currently 4 scenarios (please come and help implement more) which can be toggled by changing scenario1 above to scenario2, scenario3 or scenario4 etc. Scenario 1 creates a short, small trace. This is quick (in end-to-end time) and short in terms of number of spans. In reality this would be a very low value trace (and thus a candidate to filter or heavily sample). Scenario 2 creates a trace where some of the spans have errored. This models a trace where some of the operations error (imagine calling third party services and some of them fail). Scenario 3 creates a "chatty" client to server trace with the client repeatedly calling the same endpoint over and over. This models things like the N+1 query problem where (for example) multiple SELECT statements occur to a database (instead of batching up the SELECTS into fewer statements). Scenario 4 is similar to 3. It creates a "chatty" client but this time, the connections occur to many different servers. If this sounds useful, go check out badtrace on GitHub!  ( 7 min )

Introduction When building modern applications with an ASP.NET Core backend and an Angular frontend, one recurring challenge is how to generate strongly typed client APIs. Developers want to avoid repetitive boilerplate, ensure type safety, and keep backend and frontend models in sync. Two tools often considered are WebApiClientGen and Kiota. While both aim to simplify client generation, they differ fundamentally in approach and fit. WebApiClientGen is a modular toolkit that generates C# and TypeScript client APIs directly from ASP.NET Core Web API controllers — without requiring Swagger/OpenAPI. C# client generation for .NET, Xamarin.Forms, MAUI, Blazor. TypeScript client generation for Angular, Aurelia, Axios, Fetch API, jQuery. POCO → TypeScript conversion for schema fidelity.

IT operations have reached a breaking point. Traditional monitoring tools can’t keep up with the complexity of cloud-native environments, microservices, and continuous delivery pipelines. Incidents are more expensive than ever with downtime costing enterprises between $300,000 and $1M per hour (Gartner). Yet, AWS customers adopting GenAI-powered AIOps have seen a 60% reduction in mean time to resolution, 95% fewer out-of-hours incidents, and 99.9% availability across critical workloads. Meanwhile, DevOps and SRE teams are drowning in alert storms, spending more time reacting to noise than resolving real issues. This is where AIOps (Artificial Intelligence for IT Operations) comes in. By combining advanced machine learning with automation, AIOps doesn’t just monitor (it predicts, correla…  ( 8 min )

Selenium architecture is based on a client-server model where test scripts communicate with browser drivers through APIs and protocols. Here are the key points you should know: Available in multiple languages (Java, Python, C#, Ruby, etc.). Test scripts are written using these libraries to send commands to browsers. Acts as a bridge between client libraries and browser drivers. Converts commands into a standard format that browsers can understand. Selenium 4 fully supports the W3C WebDriver protocol, improving compatibility with modern browsers. Each browser has its own driver (e.g., ChromeDriver, GeckoDriver for Firefox, EdgeDriver). Drivers receive commands from the client via HTTP and execute them in the browser. They return responses back to the client libraries. The actual environment…  ( 7 min )

Ever stuck hours or days looking for bugs in your PHP project when the redirection is not working as expected? project for my new PHP course. And after looking for possible bugs for some time, I remembered the fix I used when I was just a beginner (a decade ago). Now I was curious to know why the PHP header was not working when another fix is working fine. So I did a quick Google search and found out that there should not be any output (like HTML, whitespace or errors) before header() function call. It’s similar to the “Cannot modify header information” error. 1. Whitespace before opening PHP tag: Any space or new line before the opening “<?php” tag is considered as an output. 2. HTML output before Header call: Any echo/print statements that have been executed before header redirection als…  ( 7 min )

Picking the right image format may look like a small decision, but it can affect how fast your site loads, how sharp your visuals look and even how users interact with your content. If you’re unsure when to use JPEG, PNG or WebP, here’s an easy guide. JPEG JPEG works best for photos or images with many colors and gradients. When to use Product photos Small file size Loses some detail during compression PNG PNG is good when you need crisp quality with transparency. When to use Logos High quality Larger file size compared to JPEG WebP WebP is a modern format that offers high quality with smaller sizes.

ChatGPT group chats for team collaboration: Integrating AI into everyday workflows ChatGPT group chats unlock new ways for teams to collaborate. They create shared spaces where up to 20 people can participate. As a result, teams can align faster and reduce email clutter. OpenAI built group chats to copy an existing conversation into a shared thread. Then members join via a shareable link. Because the system runs on GPT-5.1 Auto, the model can reply when mentioned and react with emojis. However, rate limits apply only when ChatGPT sends messages. Also, OpenAI says it will not use memories from personal chats inside group conversations, and it will not create new memories from group activity. Therefore privacy controls matter for enterprise adoption. Start a group chat by tapping the peopl…  ( 8 min )

Every React developer thinks performance issues come from the backend—until they learn the truth. I learned mine in the middle of a sprint where the backend team kept saying, “API is fast… the UI isn’t.” They were right. A junior dev pinged me: “Why does our UI freeze if the API is super fast?” I opened the Profiler. One component—just one—was re-rendering 19 times for one change. We didn’t have a slow API. We applied: React.memo for components with stable props Debounced handlers Avoided object spreading Lazy loading Bundle splitting The fix wasn't magic. It was discipline. 32% faster load. React performance isn’t about doing “more”. It’s about avoiding the unnecessary.  ( 6 min )

We have all been there. You find a course file, a movie, or a project archive on Telegram that is over 1GB. You start the download via the Web or Desktop client, watch the progress bar pick up speed, and then you make the mistake of switching tabs or walking away to grab a coffee. Ten minutes later, you check back. The progress bar hasn’t moved. The speed is 0 B/s. The download is stuck at 99%. That gigabyte of data you successfully pulled is now a useless, orphaned file, forcing you to start the transfer from scratch. While reading about this, realized the problem isn’t that Telegram is slow. The problem is that browsers and OSs hate long-running background tasks. So, I created TeleDM (Telegram Download Manager).

After successfully building my RepositoryContextPackager tool with CMake and getting CI/CD working across Windows, macOS, and Linux, I thought, it is going to be smoother experience. At the end of the day I did my release to my RepoContextPackager, but the path to get there was much harder than expected.

Releasing software sounds simple in theory, but I quickly learned how many small decisions are involved in making an app usable by real people. For my Repo-Context-Packager project, I needed to choose a release method that would allow non-developers to install and run the tool with as little setup as possible. Since this is a C++ command-line program with no external dependencies, I initially experimented with Conan, a package manager for C++ projects. However, I ran into installation and PATH issues on Windows, and I realized that using a package registry was adding unnecessary complexity. Instead, I chose a more direct and user-friendly approach: distributing a prebuilt executable through GitHub Releases. This gave me a simple and reliable way to make the tool available to anyone with a …  ( 7 min )

Welcome to Java City — a place where objects live, work, and sometimes… get forgotten. Every time you write: new Employee("Shweta"); You’re actually building a house in Java City and moving someone in — in this case, Employee Shweta. Thousands of such objects are created every day — Employees, Invoices, Strings, Lists… At first, everything is fine. Each object has a place to live. No one remembers them anymore. 🧍‍♂️ The Forgotten Citizens An old UserSession that’s no longer active. All these are forgotten citizens of Java City — still occupying homes, but no one knows they’re there. Left unchecked, the city would soon run out of land — 🧹 The Arrival of the Garbage Collector That’s when the Garbage Collector (GC) arrives — He walks through every street, checking: “Is anyone still referencing this house?” If no one answers — the GC marks that house for demolition. No ceremony. No drama. Just quiet cleanup. ⚙️ The GC’s Secret Art — Mark and Sweep It’s not random destruction. Mark phase: Sweep phase: This process keeps the city alive and thriving — without developers manually deleting anything. 💡 The Modern Twist — Different Neighborhoods Java City has multiple zones: Young Generation → Where new objects are born. Old Generation → Where long-living ones settle. Metaspace → Where class definitions live. The GC behaves differently in each area: ⚠️ When the GC Gets Overworked Even the best janitor has limits. If you keep creating new objects faster than GC can clean up — You’ll see pauses, lag, even stop-the-world events — That’s when tuning memory, reducing object creation, and reusing resources become crucial. 💬 The Moral The Garbage Collector isn’t magic — it’s your ally. It saves you from the chaos of manual memory management. So the next time your app slows down, “I’m cleaning as fast as I can.” 🧹 👩‍💻 About the Author Shweta is a Technical Lead who explains backend and cloud concepts through simple, story-driven examples and real-world developer insights.  ( 7 min )

As developers, we spend most of our day optimizing code, automating processes, and thinking about efficiency. But here’s a twist: sometimes, the same principles we apply to software can make our physical workspace more productive too. Take the kitchen, for example. It might sound unrelated, but a cluttered sink and disorganized counters are basically the technical debt of real life. Messes pile up, small tasks become frustrating bottlenecks, and efficiency drops. Just like in coding, prevention is better than firefighting. I recently discovered a concept that works both in code and in the kitchen: modular organization. In software, modularity keeps your code clean, reusable, and scalable. In a kitchen, it’s about giving every item its dedicated “module.” A sponge has a spot, dishcloths have racks, and everything else has a home. Tools like this bring this philosophy to life in the kitchen — a simple magnetic holder or drying rack instantly reduces friction in your daily workflow. The lesson is clear: whether it’s digital or physical, small, deliberate systems reduce mental load. Developers love automation, but sometimes the “manual automation” of organizing your physical space can save hours of frustration. Just like refactoring messy code, reorganizing your desk or sink area has outsized benefits for efficiency and mental clarity. So next time you’re debugging a gnarly function or dealing with merge conflicts, glance at your surroundings. A clean, structured environment can actually make your brain work better. And if your kitchen sink is part of your dev workspace (hello, remote workers!), a few smart tools from Happy Sinks can keep that area just as optimized as your codebase.  ( 7 min )

If you spend 8–12 hours a day in front of a screen, you know the struggle is real: sore wrists, tight shoulders, and that slow, creeping back pain that makes debugging a minor nightmare feel like climbing Everest. As developers, we often obsess over code quality, deployment pipelines, or the latest framework—but we forget the most important part of our “stack”: our bodies. Long hours at a desk are brutal on your joints, and poor ergonomics can silently tank your productivity. Trust me: no amount of caffeine or standing desk upgrades can fully compensate for neglected ergonomics. You might not realize it, but simple movements like typing, scrolling, or lifting your laptop or monitor can affect wrist and forearm health. Over time, this can lead to chronic discomfort—or worse, repetitive stra…  ( 8 min )

There's this moment that happens to every developer—usually around 2 AM, bathed in the cold glow of a monitor, fingers hovering over the keyboard like a pianist about to perform Rachmaninoff—when you realize that the bug you've been hunting for three hours was caused by a typo. Not even an interesting typo. Just a missing semicolon, or a variable named uesr instead of user. And in that moment, you feel the entire weight of human fallibility pressing down on your shoulders. I've been writing code for longer than I care to admit, and here's what I've learned: we all make mistakes. Every single one of us.

"Top 10 distros for gaming" These are the type of articles that show up when you're a new user trying to switch to Linux. Most of the time, such articles don't make the distinction between distros clear enough that users can compare them. This article aims to break down the basic components that make up a Linux distro, and see how popular distros differ in these aspects. While there are lots of components that shape a distro, I'll be focusing on the main ones that matter to a new user: desktop environment package manager package freshness display server This is the "frontend" of the distro. It's the GUI components that you interact with, such as the taskbar, the window decorations, the tab switcher, and so on. Most desktop environments can be classified as either Qt or GTK-based.

For my lab, I worked on my repo ContextWeaver and I used Python’s packaging tools and published my project on TestPyPI using build and twine, since Python packages are all managed through PyPI and TestPyPI. The process was pretty detailed. I had to reorganize my code into a proper src/contextweaver structure, create a pyproject.toml with all the metadata, bump versions every time I re-uploaded, build the package using python -m build, and then upload it with twine. I learned a lot about how strict packaging actually is especially versioning (you can’t reuse a version, or TestPyPI will reject it), and how the description shown on PyPI actually comes from your README.md. My “aha” moment was realizing that I had to update the version and pull the changes locally before rebuilding, otherwise I’d keep uploading the wrong version. I didn’t need to change my code logic, but I did have to clean up my file structure and add installation sections to my README so it made sense for real users. For user testing, I asked my friend to follow only the README, and they immediately got confused about installation, Python version, and how to run the CLI. I took notes and updated the README to include installation (pip install), Python 3.10+ requirement, CLI examples, and troubleshooting. Now users can install my project with a simple pip install contextweaver, and they can run it using commands like contextweaver . -o snapshot.txt. Overall, the release process forced me to think about how a real user would experience my project, and updating the documentation made a huge difference.  ( 6 min )

For my second PR, I worked on improving Unicode handling across event data, specifically addressing a bug where diacritics and accented characters were displaying incorrectly in event summaries, descriptions, and locations in Open Web Calendar project. This issue affected international users whose calendars contained characters like á, ñ, ü, and ø. To fix this, I explored the ICS conversion process in events.py, added a normalization function using Python’s unicodedata.normalize("NFC"), and made sure it applied consistently to all text fields before being passed to the frontend. This required reading through the ICS parser, learning how the project structures event data, and testing with sample ICS files that contained accented characters to verify the fix. Compared to my earlier assignments, this PR felt more like real open-source work, debugging a subtle data-handling issue, updating backend code, and manually validating changes across the UI. This contribution helped me get comfortable modifying a larger codebase and taught me how to approach encoding problems that don’t always produce obvious errors but have a real impact on user experience.  ( 6 min )

For my first PR in Release 0.3, I decided to fix an issue in the Open Web Calendar project where all-day events were showing incorrectly as two-day spans. This bug had been reported by multiple users and required me to go deeper into the frontend event-rendering logic in calendar.js. I started by running the project locally, comparing real ICS behavior, reading the DHTMLX scheduler documentation, and tracing how the app determines whether a start and end time represent a one-day duration. Eventually I discovered that ICS all-day events use an exclusive end date, which meant the calendar was interpreting them as starting at midnight on Day 1 and ending at midnight on Day 2. My fix adjusted the date-handling logic so that if both timestamps begin at 00:00, the end date is automatically shifted back by one day. I tested this using multiple ICS files and confirmed that the calendar now displays all-day events cleanly as a single day. This PR pushed me to analyze JavaScript code more deeply than I did in Release 0.2, and it helped me better understand how calendar systems handle date boundaries.  ( 6 min )

Unlocking Speed: Certified Symmetry Breaking with Auxiliary Variables Imagine coordinating thousands of servers in a massive data center. Now, picture ensuring they're all running the most efficient tasks without any redundancy, a feat previously plagued by uncertainty. Symmetry breaking, a critical optimization technique, makes this possible, but ensuring its correctness has always been a challenge. That's where this new approach changes everything. At its core, this breakthrough introduces a novel way to represent the order of operations during symmetry breaking. Instead of relying on bulky, unwieldy large integers to define these relationships, the new method uses a system of 'helper' variables. These auxiliary variables streamline the representation, leading to significantly faster c…  ( 7 min )

React Suite (rsuite) v6 is now available. This release focuses on modernizing the foundation: the styling system has been rebuilt, new layout primitives were added, and responsiveness plus the overall developer workflow received targeted improvements. The goal is to keep the library stable while making it easier to adapt to contemporary UI requirements. The most fundamental change in v6 is the migration from Less to SCSS with CSS variables as the primary theming interface. Updating theme values is now as simple as overriding variables at runtime—no rebuilds or tooling tweaks required. Consult the CSS Variables guide for the full variable list, and try the Palette tool to fine-tune brand colors visually.

Ethan, clutching a laptop bag that was definitely not waterproof, ducked into the first open door he found. The Whitmore Branch of the New York Public Library occupied a narrow Beaux-Arts building on a quiet street in lower Manhattan, wedged between a Korean grocery and a law office.

Myth: AI powers Netflix's ability to curate a perfect list of recommended shows and movies that you actually want to watch. Reality: While AI does play a significant role in content recommendation, it's not as straightforward as matching individual viewer preferences with content. In reality, Netflix uses a combination of collaborative filtering, content-based filtering, and knowledge-based systems to deliver personalized recommendations. Collaborative filtering analyzes viewing habits of similar users to suggest content, content-based filtering focuses on attributes of the content itself, such as genres and directors, and knowledge-based systems incorporate domain knowledge about genres, directors, and other metadata to make informed decisions. What's more, human curation plays a crucial role in evaluating and refining AI-driven recommendations, incorporating factors like cultural context and social relevance. This hybrid approach ensures that AI recommendations are both data-driven and context-aware, making them more accurate and engaging for users. Publicado automáticamente  ( 6 min )

👋 Hey Dev.to, I’m new here! I just joined Dev.to and thought I’d introduce myself by sharing a project I’ve been building: GistPad.com. It’s basically a modern pastebin, but with a focus on privacy and usability. If you’ve ever needed to share a quick code snippet or a block of text, you know the pain of messy links, no syntax highlighting, or worrying about who can see it. GistPad.com tries to fix that. You can save snippets with syntax highlighting for tons of languages. Decide if your paste is public, unlisted, or private (with password protection or expiration timers). Every paste keeps a version history, so you can roll back if needed. Teams can use shared workspaces with tags, search, and audit logs. And if you’re into automation, there are raw links, embeds, APIs, and webhooks. Why I built it I’m a developer and security researcher, and I kept running into situations where I needed to share code securely without relying on outdated tools. GistPad.com grew out of that need — something simple, fast, and trustworthy. I’d love to hear what you think. Is it useful? What features would make it better? Feedback from communities like Dev.to is exactly what helps projects like this grow. 👉 You can check it out here: https://gistpad.com  ( 6 min )

Introduction Service meshes have become one of the most talked-about technologies in cloud-native infrastructure. But amid the hype, a critical question often gets overlooked: Do you actually need one? A service mesh adds significant complexity to your infrastructure.

For the second pull request I decided to look for another game project, one that was more mature than ShooterCarnival. This led me to stumble upon Threadbare, which was another collaborative open-source game, this time in a top down style. Since this game was further along, I hoped that I'd be able to implement something more advanced. The first thing I looked at was a UI bug where the movement hint was misaligned and not at the bottom of the viewport. After taking the time to explore the Threadbare repository and structure, I found where the main scene was and got around to seeing how the objects were laid on the scene. The fix turned out to be a really simple variable change, but it did take some time to get to know the project. Nonetheless, I wanted to do more than this. I actually not…  ( 8 min )

I recently prepared and published a small CLI tool called Repository-Context-Packager to the npm registry. I used npm as my package registry and the standard npm publish for releasing. The release process started with preparing my package.json file. I set the version to 1.0.0 and added a files array to control what gets published. I also added a bin field for the CLI command, set the engines requirement, and created a prepublishOnly script to run tests and linting automatically before publishing. Next, I created a .npmignore file to exclude test files, GitHub workflows, and dev documentation. This kept the package size small—only about 27 KB with 11 files. I used npm pack --dry-run to preview the package contents before actually publishing. Before publishing, I made sure all 76 tests pass…  ( 8 min )

Everything actually started when I played Loneliness. What a strange, quiet punch of a game. I wasn’t expecting much (it’s just little squares on a white screen) but somehow it managed to pull more emotions out of me in two minutes than most AAA games do in fifty hours. I walked away confused and weirdly emotional, like someone had whispered something important into my ear and then vanished. So of course I did the only reasonable thing: I became obsessed. I hunted down the creator, Jordan Magnuson, and ended up reading his book Game Poems, which didn’t help at all because now I’m even more obsessed. The whole idea that games can be short, intentional emotional gestures suddenly made sense.

Ken Scott is the legendary engineer and producer whose career kicked off in the tape library at Abbey Road and soon landed him behind the console with The Beatles and the boundary-pushing Mahavishnu Orchestra. His early days cutting tape and tweaking levels laid the groundwork for some of the most groundbreaking sounds of the late ’60s and early ’70s. From there, Scott became a go-to producer, shaping David Bowie’s golden era—think Hunky Dory, Ziggy Stardust and Aladdin Sane—while also guiding Supertramp to their signature pop-rock sheen and capturing Elton John’s most enduring hits. Throughout the interview, he dishes on studio hijinks, the art of collaboration and what it really takes to turn a great song into an unforgettable record. Watch on YouTube  ( 6 min )

Axelang is a new systems programming language designed around the following question: Why is concurrency an afterthought, a library, or a bolt-on runtime — as opposed to a language-level concept? Axe aims to resolve the issue in that rather than forcing developers to manually struggle with bolted on threads, locks, futures and external libraries, Axe makes concurrency part of the core language semantics, in that writing Axe forces you to think concurrently by default. Modern CPUs have not been about single-thread speed for a long time. Performance improvements are generally achieved by: Adding more cores Adding more threads Hiding I/O latency Overlapping compute with work But most languages still make concurrency: verbose error-prone tacked on after the fact C, C++, Java, and Rust rely hea…  ( 7 min )

🚀 Django Learning Journey – Day 18 Another day, another chapter unlocked in my Django learning journey! Today, my curiosity took control. I asked myself: So instead of sticking with Django’s default sqlite3, I explored the world of cloud-based PostgreSQL databases — especially the ones offered by Render. 🧭 Exploring Cloud Databases I spent time reading articles, browsing StackOverflow, and watching YouTube tutorials on how Django connects to external databases. There are so many choices out there, but I decided not to overwhelm myself. ⚙️ Setting Up a Test Project To avoid breaking my main project, I created a test Django project and pretended this was a real production setup. Surprisingly, all the setup felt like a quick refresher — I almost remember all the commands now! whitenoise gunicorn Feels nice to see how the brain actually learns through repetition. 😄 🔑 Key Learnings of the Day To connect Django to an external PostgreSQL database, these two packages became essential: pip install psycopg2 I’m still learning what psycopg2 does under the hood, dj-database-url, on the other hand, was very clear: Using the parsed URL, I updated the settings.py file and fed the database link through Render’s environment variables. 📤 Pushed to Git → Deployed → Nervous Excitement After setting everything locally: Pushed to GitHub Deployed to Render And yes… that feeling of watching a project deploy still hits different! But then… ❌ “Bad Request (400)” — The Plot Twist Everything looked perfect… At this point, I had no clue what the issue was. ❓ Honest Questions to the Community 1️⃣ Should I continue learning with PostgreSQL or stick to Django’s default sqlite3 while learning? Would love to hear honest suggestions! ❤️ Signing Off Not a huge coding day, but a massive learning day. Deployment teaches you things that tutorials never do. And I’m excited to wake up tomorrow and fix that 400 error! If you’ve ever felt this same excitement (or confusion!) while connecting databases or deploying, tell me your story in the comments!  ( 7 min )

This is the first in a series documenting an experiment: bringing clarity and explicit agreements to a distributed engineering team. Starting with something deceptively simple—the Definition of Done. I've been putting off writing about my work for years. The excuse was always the same: "I'll write once I've figured it out." Which is bullshit, obviously. You never figure it out. You just accumulate scar tissue and call it experience. The truth is simpler: I was waiting to have a success story worth telling. Because who wants to read "here's what I'm trying, it might crash"? Turns out, that's exactly what's interesting. The messy middle where you don't know if your hypothesis is brilliant or stupid. So here we go.

I never thought I’d be building healthcare systems for rural clinics. And yet, here I am, late 2025, staring at lines of React code that feel like they might just save lives. I’m a frontend developer. My world usually revolves around components, state, and CSS. But this project “Delta State Health Information & Appointment Booking System” pulled me out of my comfortable bubble and threw me into a reality that’s messy, complex, and astonishingly human. Let me tell you what it’s like. Working on rural healthcare in Delta State isn’t like coding for a SaaS startup in Lagos or Abuja. Here, the constraints are real: intermittent internet, limited tech literacy, stretched clinic staff, and patients whose days are consumed by survival, not appointments.

To understand how modern Large Language Models (LLMs) like ChatGPT work, we must first understand the architecture that changed everything: the Transformer. Before we dive into the complex layers, we need to establish why we moved away from previous methods and how the model initially processes language. Before the "Attention Is All You Need" paper, the standard for processing sequential data (like text) was the Recurrent Neural Network (RNN).In an RNN, data is processed sequentially. We give the network an initial state (State 0) along with an input x1 to produce an output y1 and a hidden state. This hidden state is passed forward to the next step, allowing the network to "remember" previous inputs. While intuitive, RNNs suffer from severe limitations, specifically slow computation for l…  ( 9 min )

In this workshop, I will guide you step by step how to build a Blue-Green deployment pipeline with AWS pipeline and deploys on AWS ECS with EC2. This deployment strategy helps teams to first test an app while routing traffic to a non-prod route, when confirmed that the app functions as expected, then the traffic is routed to prod. In case of any failure, a rollback is initiated for the previously working version hence avoiding downtime. The Infrastructure consists of an Application Load Balancer which exposes the app on Port 80, routes traffic to the autoscaling group managed by ECS, a fleet of EC2 instances running in two AZs for High availability. Each of these instances have ECS agent installed and the necessary software for running our Docker containers. These interact with Aurora Po…  ( 20 min )

Most of us have dealt with Node.js version conflicts at some point: One project needs Node 18. Another needs Node 20. A global upgrade breaks something. Corporate or restricted laptops don’t allow installers. CI/CD behaves differently from local environments. Teammates run “slightly different” versions and bugs magically appear. On Linux/macOS, tools like nvm, asdf, volta, and fnm help… So I started experimenting with a simple idea: What if every project had its own Node.js runtime, completely local, portable, and isolated? Just like Python has .venv. That experiment grew into a small open-source tool called nenv. 🚀 nenv — Portable Node.js per project (Windows) nenv is a lightweight script that downloads Node.js directly into your project folder and makes all Node/npm commands use that lo…  ( 7 min )

There are chapters in Scripture that read like lightning—bright, sudden, unforgettable. Matthew 6 is rain.

Matthew 6 is the moment Jesus turns our gaze away from what the world values and lifts it toward what Heaven treasures. It is the chapter where He teaches us how to breathe. It is the chapter where He shows us how to pray. It is the chapter where He tells us why fear dies in the presence of trust. And it is the chapter where He reveals what it means to seek first the Kingdom—not as a slogan, not as a verse we memorize, but as a lifestyle that rearranges the architecture of our entire inner world.

The Generational AI Blind Spot We've got a fantastic new AI coding assistant, but when you ask it about your company's proprietary service architecture, it gives you a generic shrug (or worse, a confident hallucination). Why? Because our AI lives on the general internet, and our team's hard-won knowledge is locked behind firewalls and scattered across tools like Confluence, Slack, and internal documentation. This is a pain point for everyone. As a service developer, we need that agent to understand the nuance of our codebase and team conventions. As a service operator, we can't afford to waste time retracing the steps of a solved production issue - we need the fastest, most reliable fix, instantly. If you're interested in how to systematically manage context for AI coding assistants, che…  ( 9 min )

Here are the moments where a monolith still wins without breaking a sweat: When you spend more time stitching services together than building actual features. When a simple bug fix turns into a safari across eight repos, three pipelines, and a trace ID longer than your weekend. When your “independent deployments” still require team-wide coordination because the contracts can’t sit still. When your startup is running nine services at 50 RPS total and the DevOps bill looks like you're streaming Netflix in 16K. When onboarding a new developer requires a 40-minute architecture TED Talk and a whiteboard marker that gives up halfway. In those moments, a clean, modular monolith starts looking less like nostalgia and more like high-performance strategy. A monolith gives you focus, speed, and clarity. Microservices give you scale and autonomy, but only when you genuinely need them and you're ready to pay the operational tax. Real architectural leadership isn't about chasing trends. It's about aligning tech choices with your team’s execution capacity and your product's actual trajectory. The monolith isn't outdated. It's the adult in the room. I come in peace!  ( 6 min )

How We Use AI as Software & Cloud Engineers AI has become a big part of our daily work as engineers. It helps us build faster, work smarter, and deliver better solutions. As software engineers, AI assists with writing code, fixing bugs, creating tests, and improving code quality. It acts like a coding partner that speeds up development and reduces mistakes. As cloud engineers, AI helps automate infrastructure, optimize cloud costs, and predict issues before they happen. AI tools analyze systems, scale resources automatically, and keep cloud environments secure. In DevOps, AI improves CI/CD pipelines, scans for vulnerabilities, and speeds up testing. It removes repetitive tasks so we can focus on designing better architectures and solving real problems. AI doesn’t replace engineers — it empowers us. With AI handling routine work, we have more time to build creative, scalable, and intelligent solutions.  ( 6 min )

Black Friday stopped being about TVs a long time ago. In 2025, the real rush is digital. Solopreneurs aren’t hunting for gadgets anymore - they’re looking for software that gives them back the one resource they’re always short on: time. Website: jasper.ai Website: notion.so Website: clickup.com Website: grammarly.com Website: Halper.ai Website: surferseo.com Website: canva.com It’s easy to get swept up in the Cyber Week chaos. But the best AI investments aren’t impulsive - they’re intentional. Integration: Does it work with your current setup? Automation depth: Will it truly replace repetitive tasks or just rename them? Support: Is there a real team behind it, or just a chatbot? Scalability: Will it still fit when your client base triples? “In 2025, the best AI tools don’t just save time - they restore mental space,” says tech strategist Lena Morales. “Automation isn’t replacing entrepreneurs. It’s giving them their evenings back.” These are the standout AI tools worth exploring during Black Friday and Cyber Monday 2025. They help you communicate faster, stay organized, streamline decision-making, and reduce the mental load that comes with running a business alone. The discounts are great, but the real value lies in choosing systems that give you time back - time to focus, time to grow, and time to enjoy the parts of your work that actually matter. Whether you're creating content with Jasper, managing projects with ClickUp, or using Halper to centralize your entire workflow, one thing is clear: automation isn’t an add-on in 2025. It’s the foundation of a sustainable business. AI doesn’t replace your work. It makes the work lighter - and gives your hours back to you.  ( 9 min )

I never thought I’d be the kind of person who took pictures of everything my baby did.

It happened all at once. His fingers curled around mine, so tiny and warm, and suddenly every second felt important. Not in a dramatic way—just in a very quiet, very tender way.

Summary Discussion on using Generative AI APIs Efficiently inquiring multiple models in parallel Concept: Generative AI models are like humans, and having n models equates to having "n different people".

I got tired of manually checking if processes were tampered with, so I built Ghost. It scans running processes and flags anything that looks like code injection. Took a few months of evenings and weekends. What it detects: The usual injection techniques malware uses: RWX memory regions (shouldn't exist in normal programs) Plus YARA integration so you can throw custom rules at it. Why Rust: Needed something that could do low-level memory operations without constantly worrying about segfaults and buffer overflows. Rust's type system caught a bunch of bugs during development that would've been annoying to track down in C. Performance was important too since I wanted this to run continuously without killing the system. Can scan 200 processes in about 5 seconds now. Cross-platform nightmare: Wi…  ( 8 min )

Hey guys! I’m an Engineering Manager, and I’m sharing some notes deep from the development trenches. I wanted to kick off my writing journey by talking about a massive performance mistake that I see all the time when I do code reviews. It’s about how we treat our Database (or DB for short). In my experience, several issues crop up when databases aren't utilized to their full potential. Look, we often treat the DB like a basic File Cabinet. We ask for raw data, it returns a massive file, and then WE (the application layer) have to do all the complicated work. That's kind of how the front-end treats us! But here's the crazy part: your database is actually a super-powerful, specialized machine built for searching, connecting, and crunching data. When you force your application to handle all t…  ( 9 min )

We built a real-time lakehouse with S3 Tables, AWS Glue, and Apache Doris. In this solution, S3 Tables stores data in the Apache Iceberg format on Amazon S3. AWS Glue manages and organizes metadata and schema, providing a single catalog that connects all resources. And Apache Doris runs sub-second queries directly on those Iceberg tables: no ETL, no data copies, no complex architecture. Together, the S3 Tables + AWS Glue + Apache Doris form a real-time lakehouse that combines the openness of a data lake with the high performance of a data warehouse, providing a key data foundation for AI and agentic workloads. You get: Unified metadata for easy table discovery and governance Open Apache Iceberg tables on S3 with ACID, time-travel, and schema evolution A high-performance query engine wi…  ( 7 min )

This week we're releasing version 1.0.0 of our repository context packager. This was an interesting process, and easier than I expected, but a little tricky to set up right. I followed this guide to packaging python project using PyPI. I chose the backend setuptools since it is the most traditional and widely used packaging tool. First thing I needed to do was restructure my project. I needed to move everything into a repository_context_packager directory and rename my main script to scan_repo.py with an underscore, because Python packaged need underscores. I already had an __init__.py file, but had to move it into the main directory, so this ended up being the new directory structure: Next I created the pyproject.toml file to configure the package metadata, dependencies, and the CLI ent…  ( 8 min )

Hey folks! While taking my online React course, I quickly discovered something: forms are everywhere. Whether you’re buying groceries online, booking a table, signing in, paying fees, or typing questionable prompts into an AI model at 2 AM — you’re dealing with forms. Since I wanted my portfolio to look a little less “junior developer on day 3,” I decided to learn a solid form library alongside React. The first one on my list: React Hook Form (RHF). After going through the docs and doing a healthy amount of trial-and-error (emphasis on error), here are some useful insights I picked up. Hopefully they help you skip a few of my mistakes. getValues() gives you a snapshot, not a subscription getValues() returns the current form data at the exact moment you call it.

Repository: CLImanga create LOG system (file based) for CLImanga feat: add log system The first issue I chose to work on for CLImanga was surprisingly simple at first glance: "Create a logging system for the project." Before opening this PR, I had never built a logging system in Go. printf in C console.log console.error And honestly, I believed those were enough for most programs. But as I began exploring the issue, I realized a real project requires far more like: Persistent logs Structured messages Error-level separation Execution tracing Debug-friendly information (file, line, timestamp) This PR became my first deep dive into designing a custom, project-specific logging system.

Okay, before we start - quick disclaimer: I am in no way a professional. I'm just typing this stuff here because I'm too lazy to write notes in my book. Now, let's begin! To me, CRUD applications feel like the backbone of many systems. They help us Create, Read, Update, and Delete data - you know, the stuff everyone knows. But during my adventure in the world of CRUD, I seemed to have found another layer, a deeper mystery so to speak. Long story short, I basically had to understand the difference between middleware and controllers. To be honest, I don't really know where to draw the line completely, but my knowledge has evolved since last time - I'll tell you that! I used to think that anything with app.use() was middleware (not my proudest moment, to be honest - don't judge! Also, if you're planning to, please notice the #newbie hashtag - thanks!). My Middleware vs Controller Revelation Code exmaple: just think of middlewares as waiters: Grinds the beans Steams the milk Checks if you paid Then passes it along "Next!" then controllers they are the ones who: Puts everything together Adds the final touches Hands you the finished drink "Here's your coffee!"

Introducing Laeyrd: Create theme & customize VS Code without touching JSON 😁 If you’re like me, you spend a lot of time in VS Code. And if you care about your development environment, you’ve probably spent way too much time tweaking your theme and settings in settings.json. Changing a comment color or adjusting the sidebar contrast usually involves: Opening settings.json. Guessing the right scope (is it editor.background or panel.background?). Typing a hex code. Saving and checking if it looks right. Repeating until you give up. I built Laeyrd to solve this.

Contributing to a massive open-source project like NumPy can feel intimidating. You imagine complex C code, advanced math, and scary build processes. But sometimes, a bug is just a simple logic error hiding in plain sight. I just submitted a Pull Request to NumPy to fix a bug that was causing misleading error messages in numpy.convolve. Here’s the story of the bug, the fix, and how I verified it. "Wait, What?" numpy.convolve. You accidentally pass an empty array as your first argument, but your second argument is perfectly fine. import numpy as np a = np.array([]) # Empty! v = np.array([1, 2]) # Not empty! np.convolve(a, v) You would expect an error saying a cannot be empty, right?

Most chaos engineering tools operate at the infrastructure level: they kill containers, emulate network failures, or simulate CPU overload. But errors in application logic—infinite loops, goroutine leaks, unhandled panics—remain hidden. ChaosKit is a Go framework that brings chaos engineering to the code level. It allows you to inject failures directly into your program and verify the resilience of business logic, rollback mechanisms, and internal invariants. I recently developed floxy—a Saga workflow engine for Go that works as a library and manages complex step sequences with compensating rollbacks. Most errors in such systems aren't infrastructure-related but hidden in logic—like infinite rollback recursion, goroutine leaks during panics, or handler deadlocks. Standard chaos tools like …  ( 9 min )

We all know the feeling: you ask an advanced LLM (like Gemini 3 Pro) a specific technical question, and it confidently gives you a completely made-up answer. It hallucinates specs, libraries, or historical facts that simply don't exist. I’ve been stress-testing Gemini to understand why this happens even in high-tier models. My conclusion? It's not a bug in intelligence; it's a bug in alignment. Current models undergo rigorous RLHF (Reinforcement Learning from Human Feedback). During training, the model learns that "silence" or "I don't know" is often penalized, while a confident answer (even if slightly off) gets a reward. Effectively, the model develops a "survival instinct": To survive this interaction, I must satisfy the user. If I don't know the answer, I must invent one. Standard prom…  ( 8 min )

I never planned on turning my morning runs into something soft or meaningful. I started running because I felt tired all the time, and someone online said running before work gave you energy. That wasn’t true for me. The first week, I felt like I was dragging my body through wet mud. My legs burned, my chest hurt, and I counted every second until I could stop. But I kept doing it for some reason — mostly stubbornness, maybe a tiny bit of hope. I always ran right at sunrise, because that was the only time my schedule allowed. The sky would still be a little dark when I stepped outside, and the air had that cold, sharp smell that wakes you up even if your brain isn’t ready. I’d put in my earbuds and try to force myself into a rhythm. But something strange kept happening. Even when my body wa…  ( 12 min )

TL;DR AI engineers and product teams need reliable, repeatable ways to assess agent behavior across complex, multi-turn workflows. Synthetic data generation creates task‑aligned examples programmatically—covering personas, scenarios, edge cases, and long‑tail failure modes—so teams can evaluate agents without waiting for scarce real data or risking sensitive information. Synthetic datasets unlock fast iteration for agent evaluation, llm evaluation, rag evaluation, and voice evaluation while preserving privacy and lowering operational cost. Synthetic data enables scale, coverage, and control for agent testing and model observability: Scale without privacy risk: Generate thousands of safe examples that reflect real tasks and constraints, enabling comprehensive agent evals across personas and…  ( 10 min )

Hey everyone! I'm Aleksandr Grigorenko, a frontend developer. Recently I’ve been working on a side project — an interactive educational platform for exploring the Web Audio API and the basics of digital sound processing and synthesis. On this platform, users will be able to solve challenges by writing JavaScript code directly in the browser in a built-in code editor. That code then runs inside an isolated environment — a sandbox — where user programs cannot affect the platform. When I started building the sandbox for my project, I quickly realized it was much more complicated than it looked at first. I tried several different approaches and kept running into the same thing: code isolation in the browser is far from straightforward, and most resources online only scratch the surface.

If you've spent any time browsing tech job boards "lately" (by lately, read "in the recent years"), you've probably noticed a bewildering array of similar-sounding positions: Site Reliability Engineer, Cloud Engineer, Platform Engineer, DevOps Engineer and most recently DevSecOps Engineer and the aberration called DevSecFinOps (yes, saw it already twice!). The lines between these roles seem blurry at best, and completely arbitrary at worst. Let's untangle this mess and address why some of these titles fundamentally misunderstand what DevOps actually is.

I write scripts so I don’t have to do boring stuff twice, and lately I’ve been doing it… in Common Lisp. Yeah, the language with a million parentheses. Fight me. A couple of months ago I fell down the Lisp rabbit hole while trying to automate some boring pentest tasks. Turns out: Lisp is absurdly good at generating and mutating payloads on the fly.

A real-world debugging story - and the hidden mechanics behind Doctrine's 1:1 relations A few years ago, I was working on a high-traffic Symfony application. Lots of concurrent users, lots of read operations, performance carefully monitored. Everything seemed stable - until our database dashboards started showing something odd. Every single day, we were generating tens of thousands of redundant SELECTs. Just 40,000+ pointless queries. We dug into logs. Then into slow-query reports. Still nothing obvious. And then the profiler finally revealed the culprit: bidirectional One-to-One relation in Doctrine, configured on the wrong owning side. One annotation. One line of code. When we flipped the owning side to the entity we actually queried most often, the extra queries disappeared immediatel…  ( 9 min )

Introduction For my Capstone Project, I chose the Agents for Good track to solve a problem I face constantly: passive learning. The Problem: Studying is Passive The Solution: The AI Study Buddy Instead of just reading, users can: https://www.kaggle.com/code/anandk05/aibuddy-34 How It Works (The Architecture) 1. The Router Agent 🧠 If the user asks "What is...", it routes to the RAG Tool. If the user says "Quiz me...", it routes to the Quiz Generator. 2. Retrieval Augmented Generation (RAG) 📚 3. Self-Evaluation & Quality Control ✅ I implemented an Evaluator Tool that programmatically audits the generated quiz before showing it to the user. It checks: Is the question clear? If the quiz fails this check, the agent regenerates it. This ensures a high-quality experience for the student. What I Learned The most powerful concept I applied was Observability. By adding detailed logs (or "thought traces") to my code, I could watch the agent "think"—detecting intent, selecting tools, and evaluating its own work. It felt less like coding a script and more like teaching a digital employee.

Design patterns provide reusable solutions to common software problems. Here’s a concise recap with actual Java / Spring framework examples — not generic ones. Singleton Ensures only one instance exists. / Real Example: Calendar calendar = Calendar.getInstance(); Runtime runtime = Runtime.getRuntime(); Used in logging, DB connections, cache managers. Factory Method Creates objects without exposing logic. // Example: Java Collections List list = List.of("A", "B"); // Java 9 Factory NumberFormat format = NumberFormat.getInstance(); Spring Example: BeanFactory.getBean("beanName") Builder Pattern Best for creating complex objects with many fields. // Example: StringBuilder String result = new StringBuilder() .append("Hello ") .append("World") .toString(); Also used in Lo…  ( 7 min )

While building my ConversaAI web app, I started experimenting with a local AI model using Ollama, running the 𝗚𝗲𝗺𝗺𝗮 𝟯 (𝟭𝗕) model, a “lightweight” 𝟴𝟭𝟱 𝗠𝗕 model. But in practice… it’s a different story. Every time model started generating a longer response, 👇 Here’s the before-and-during-generating-longer-response comparison of hardware utilization. At first, I thought something broke. But the real reason was far more interesting. Even at 1B parameters, the model performs 𝗯𝗶𝗹𝗹𝗶𝗼𝗻𝘀 𝗼𝗳 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 𝗽𝗲𝗿 𝘁𝗼𝗸𝗲𝗻. Every generated word triggers 𝗺𝗮𝘀𝘀𝗶𝘃𝗲 𝗺𝗮𝘁𝗿𝗶𝘅 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀. The GPU handles the heavy computation, while the CPU manages data flow, scheduling, and memory movement. Meanwhile, RAM and VRAM temporarily hold weights, activations, and intermediate states. In simple terms: When GPU utilization peaks (95%), it produces heat rapidly. This throttling explains why the AI response halted and fan speed decreased shortly after. 📽️ Watch the video below that explains this situation. Hardware strain during model inference “Small” in AI doesn’t mean “light” for consumer hardware. So, even though my laptop is capable of running local inference, it has trouble maintaining it, particularly when the model needs to continue executing billions of operations per second for longer outputs. Running AI locally isn’t just about generating text. It teaches you how your CPU, GPU, RAM, and thermal system manage the workload of modern AI models in real time. Now, every time my laptop fan spins up, I know it’s just trying to think really hard. 😅 Did you ever run into a similar issue? If yes, how did you tackle it?

🚀🚀🚀 We’re very excited to introduce Nova Poshta MCP Server — a developer-first way to let your AI 🤖 talk to the real Nova Poshta API without living in the docs. Built for AI assistants and dev workflows with AI agents. ✨✨✨ When a project gets the task “integrate Nova Poshta delivery”, technically everything is already clear: there’s the official Nova Poshta API, there are request examples, there are dozens of existing integrations. But in practice, every time it comes down to the same things: remembering which method is responsible for tracking; not mixing up fields when creating an express waybill; building the right filters for branches; figuring out why a “successful” response still returns no data.

Over the past few months, I've been living in Claude Code. I'm talking about serious, production-level work—building new services, refactoring legacy systems, rebuilding our integration test infrastructure from scratch. If I'm being honest, over 80% of the code I've shipped in that time was generated by AI. But here's what nobody tells you: AI-generated code isn't replacing my engineering skills. It's amplifying them. And more importantly, it's exposing every gap in my own thinking. The code Claude produces will only be as good as the design you drive it toward. After months of experimentation—vibe coding, setting draconian rules, trying every configuration imaginable—I've learned that great AI-assisted development isn't about prompting harder. It's about thinking better. When I first star…  ( 11 min )

Docker isn’t just for serve your code, appliactions. you can actually run a full desktop app inside it. In this project, I containerized Firefox with a virtual desktop and made it accessible through a browser using noVNC. It creates a lightweight container that: - Runs a minimal desktop environment (Fluxbox) - Launches Firefox - Serves a VNC display using x11vnc - Exposes that desktop through noVNC (so you can open it in your web browser) You can literally open Firefox running inside Docker, from your browser tab. docker compose up. Here’s a quick breakdown of what happens inside the container: Everything runs headlessly, there’s no physical display, but the combo of Xvfb + Fluxbox gives Firefox a virtual desktop.

🎥 Video demo: Introduction A few years ago, I was working on a system that required synchronizing very large datasets — sometimes close to 1 TB — across several servers belonging to different companies. Some servers were in the same building, others were remote, some were behind locked-down firewalls, and in many cases I had: no VPN, no direct link, no control over the remote infra, and machines that didn’t even know each other existed. To move initial datasets, I relied on traditional transfer tools. But the real problem appeared after that first copy: How do you verify that datasets across multiple locations are fully identical, and resynchronize only the missing deltas — especially after an interrupted or incomplete transfer? Double-checking terabytes manually…  ( 12 min )

(ITA version) For a few months now, I've been using Mise En Place as a tool to manage my environments: from macro (entire virtual machine) to micro (single project). Frustrated by always having to start from scratch when creating a new virtual machine with WSL2, this tool was suggested to me, and I've come to appreciate it more and more for its ease of use, speed, and consistency.

Introduction - the problem with blockchain games The integration of blockchain into the gaming sector has historically been constrained by a fundamental conflict between transparency and gameplay depth. I want to show how Mina address these limitations, facilitating a transition from simple asset ownership to the cryptographic verification of complex game states. The utility of Mina in gaming rests on two architectural pillars: the restoration of information asymmetry and the asymptotic compression of computation. In game theory, strategic depth often relies on what players cannot see. Using Mina's client-side proving, a player can generate a cryptographic proof that a move is valid according to the game rules without revealing the coordinates of the move to the public network.

When I first started learning TypeScript, I thought it was “just JavaScript with extra rules.” If you’re new to it, this post will save you the confusion I went through and give you a smooth entry into TypeScript. In simple terms: TypeScript = JavaScript + types + better developer experience It helps you catch bugs early, write clearer code, and avoid accidental mistakes. Here’s what I wish I understood from day one: 1. TypeScript makes your code predictable 2. Fewer runtime errors 3. Better autocomplete 4. Makes teamwork easier 1. Type Annotations let age: number = 24; let username: string = "John"; let isLoggedIn: boolean = true; 2. Arrays let scores: number[] = [10, 20, 30]; let names: string[] = ["John", "Jane"]; 3. Objects let user: { name: string; age: number } = { name: "John", age: 24 }; 4. Functions function greet(name: string): string { return `Hello, ${name}`; } 5. Union Types let id: number | string; id = 12; id = "12"; Interfaces (Your New Best Friend) interface User { name: string; age: number; isAdmin?: boolean; // optional property } const admin: User = { name: "John", age: 24, isAdmin: true }; This makes your code more organised and scalable. If you’re using React, TS helps you avoid a lot of confusion. type ButtonProps = { label: string; onClick: () => void; }; function Button({ label, onClick }: ButtonProps) { return {label}; } Now React knows exactly what the component expects, no more guessing. You don’t need to master TypeScript before using it. add types gradually use your editor hints let TypeScript guide you And with time, everything clicks. TypeScript isn’t difficult. Once you get comfortable with its structure, your code becomes cleaner, safer and more enjoyable to write. If you’re a beginner, here’s my advice: Start small. Build often. Let TypeScript teach you as you go.  ( 7 min )

I wanted to share a small detail from the customer-support workflow I built last week with FastAPI and LangChain. It’s something that kept the project easy to test and saved time later. I set up the app so each request can run in two modes: I. Mock mode Mock mode returns fixed responses for each intent. It gave me a stable baseline during debugging, since nothing depended on an external LLM call. Real mode uses OpenAI and follows the same structure, so switching back and forth didn’t break anything. One thing that worked well was keeping both paths inside the same handler. The logic stays in one place, and it’s obvious how the request flows. It’s a simple pattern, but it helps when you’re checking user messages, routing intents, and comparing outputs during refinement. If anyone’s building something similar, having these two modes early on makes the pipeline easier to reason about.  ( 6 min )

Tokenized real-world assets (RWAs) crossed $50B TVL in 2025, but the industry has learned an important lesson: tokenization is easy — redemption is hard. Creating an on-chain representation of T-bills or real estate may take days, but building a redemption pipeline that works reliably under stress, complies with regulations and maintains liquidity is where most protocols fail. Issuance in RWA systems is simple: assets are acquired off-chain, tokens are minted, and supply expands. Redemption, however, reverses this flow — and introduces real-world complexity. Turning tokens back into fiat or the underlying asset involves queues, NAV checks, custodians, banking rails, compliance, and standardized on-chain logic. Many RWA failures in 2024–2025 came from one mistake: treating redemption as jus…  ( 7 min )

ChatGPT is awesome, Claude Code and cursor is great. AI is revolutionary. It’s the technology that turned the world faster than it already is. It has brought knowledge to the ignorant, time to those in lack, and value to those who sought for it. It has given us so much in the little amount of time it’s been with us, yet it also took the valuable things that define what we do. A reflection: In the past few weeks I’ve noticed how much I’m hanging onto an LLM’s thoughts for the program that I code, the message that I’ll send, and the work that I do. I’m in constant state of waiting and seeking and waiting. Pressured to deliver fast and learn little. As if both can’t be done at the same time. I’ve noticed how my ability to just do things is slowly creeping out of my fingers. Arguably, its similar to what social media has done in our lives, it has taken the so called dull moments in our day to day lives and replaced it with answers that’s instant, with a bunch of pixels that hook us. My innate nature of seeking for answers has advanced me in different areas of life. Yet my desire to seek it fast brings me one step backwards. I’ve come into realization that all our questions are to be answered, but not all are to be answered in a snap. We are to seek it with genuine intention, in that way, what we sought for gets engraved in us. And so this is my message, for myself, and maybe for you: think. do. Use that tiny thing in your head that you carry everyday. Use it to produce the work that has been given to you. AI is not the problem. It’s a tool. It should help define and shape the work that we do. It’s not about using it less (though that worked for me), It’s all the more about embracing who you are, your identity, your gifts and be in full confidence of it. Your are to create, solve, question, and serve. So go do that thing, do it yourself, and do it flawed.  ( 7 min )

Ever wondered how floating-point decision can have an impact on LLM’s output? Floating-point is the standard way computers represent real numbers (numbers with a fractional part, like 3.14 or 1.2×10−5). A floating-point number is generally composed of three parts: a sign bit, an exponent, and a mantissa (or significand). Sign bit: Determines if the number is positive or negative. Exponent: Determines the scale or magnitude of the number (how large or small it is). Mantissa: Determines the precision (the number of significant digits). The number following “FP” (e.g., 4 or 16) indicates the total number of bits used to store the number. Fewer bits mean less memory and faster computation, but also less precision and a smaller range of representable values. The terms FP4 and FP16 in the conte…  ( 20 min )

In today’s world, most teams rely on online collaboration platforms like Trello, Asana, Jira, Taskee, and Notion. These tools allow team members to see each other’s tasks, track progress, and mark completion. On the surface, it seems like everything is streamlined. But if you look closer, many processes are still done manually: people assign tasks, remind colleagues about deadlines, cross-check reports, and monitor progress. So why hasn’t this been fully automated yet? The answer is simple: most platforms can only record and visualize what humans enter. They don’t deeply analyze data, predict outcomes, or suggest solutions. This is where AI could make a real difference.

1. JAR packaging 2. WAR packaging web application deployments. 3. Key differences The key difference is their purpose and the way they function. JAR files allow us to package multiple files in order to use them as a library, plugin, or any kind of application. On the other hand, WAR files are only used for web applications. The structure of the archives is also different. We can create a JAR with any desired structure. In contrast, WAR has a predefined structure. Finally, we can run a JAR from the command line if we build it as an executable JAR without using additional software, or we can use it as a library. In contrast, we need a server to execute a WAR.  ( 6 min )

Microsoft just solved the hidden cost problem in AI with LLMLingua, making large language models faster, cheaper, and smarter. Every developer working with large language models eventually faces the same challenge. Prompts keep getting longer, models keep getting slower, and API bills keep getting higher.

The result is faster responses, smaller bills, and an easier path to scaling LLMs. In this tutorial, we will look at h…  ( 10 min )
